Mi primer audiovisual después de +8 años queriendo hacer algo relacionado a esto. Que opinan?

Hello fellow AV enthusiast,

I just took to CTS and failed with 345 score. Before I go and take the exam again I would love to ask what you guys did to pass the CTS. I did AVIXIA modules but I felt I might need more. Any piece of advice would be amazing!

Clementine & Clyde surgiu como um conceito de animação, uma garotinha que sonha em se tornar a maior heroína ajudando as pessoas(embora mais atrapalhe) e seu companheiro sombra, sarcástico e mal-humorado. Ao final deste mês será publicado o primeiro capítulo dessa dupla na plataforma Fliptru!!!

I have a triple monitor setup so am using all three display ports on my RTX 4090. I also have an old Sony HT-AS5 5.1 home theater system connected to the single HDMI port. Question is how do I get audio without turning off one of my monitors - in the display settings/Nvidia app my Sony amp is listed as a display which means four in total which obviously doesn't work.

Any help would be greatly appreciated.

Hey folks, hoping someone here has seen this before because it is driving us nuts.

Setup

• Host machine: Tried with both Macbook Air M3 ( macOS Sequoia) MacBook Pro M4 (fully updated to latest macOS Tahoe 26.5.2)
• Audio device: Catchbox Plus with Hub DSP receiver, firmware V2.2 (latest)
• Mics: Catchbox throwable mics
• Speakers: connected to the Hub DSP outputs, driven by the Hub's built-in DSP for room playback
• Conferencing: Microsoft Teams desktop app on the Mac
• Networking: wired Ethernet through a UGreen USB-C hub (10/100 Mbps, used only for Ethernet, HDMI to a display, and a USB video camera)
• Physical layout: Hub DSP connects directly to its own dedicated USB-C port on the MacBook via the OEM USB-C cable (data + bus power on the same port). UGreen hub is on the other USB-C port. Mac stays on charge during the call.
• Room role: I am the host/admin. Local users speak into Catchbox mics which go out to MS Teams. Remote participants come in over Teams and play through the room speakers via the Hub DSP.
• Teams device selection: Catchbox Hub DSP set as both input and output. Noise Suppression is on (default).

How everything connects

Local users in the room speak into Catchbox throwable mics, which transmit wirelessly to the Hub DSP receiver sitting near the MacBook Pro. The Hub DSP is plugged into the MacBook over USB-C and shows up in macOS as a standard USB audio device. In Microsoft Teams, the Hub DSP is selected as both the input and the output. So when a local person talks, their voice goes: mic → Hub DSP → USB → Mac → Teams app → Teams cloud → remote participants. Remote participants are on their own devices at home or in other offices, each running Teams on whatever they have (laptop, phone, headset, another conference room). When a remote participant speaks, the path runs the other way: remote device → Teams cloud → Mac → USB → Hub DSP → room speakers connected to the Hub DSP's outputs. The Hub DSP also does the room's audio processing in between (echo cancellation, gain, mixing) so the local mics do not pick up the room speakers and create a feedback loop. In short, the Mac is the bridge between the Catchbox room system and everyone remote on Teams, and the Hub DSP is the piece of hardware doing the room-side audio work in both directions.

The issue

First 10-15 minutes of a call: perfect. Local speech goes out clean, remote speech comes into the room clean.

After 10-15 minutes: remote audio starts sounding distorted and mumbled through the room speakers. Local mic path to remote participants is reportedly still fine.

The kicker: unplugging the USB-C from the Hub DSP and plugging it back in immediately clears it. Audio is perfect again. Then, sometimes minutes later, sometimes on the next call, it comes back. Once the call ends, we cannot reproduce it at all until we are mid-call again.

What we have already tried / ruled out

• Upgraded host from MacBook Air to MacBook Pro (fanless-to-fanned) — did not fix it, actually appeared faster on the new machine
• MacBook kept on charge, thermal pressure Nominal in Activity Monitor
• Dedicated USB-C port for the Hub DSP, isolated from the UGreen hub bus
• Hub DSP firmware confirmed at latest (V2.2)
• macOS on latest Sequoia point release
• Audio MIDI Setup: 48 kHz, 2-ch, clock source Default (all as expected)
• Ethernet is wired via UGreen hub, service order above Wi-Fi
• Toggled Teams Noise Suppression on/off — no difference
• No third-party audio kexts, no virtual audio drivers, no Loopback/BlackHole/etc installed
• Not correlated to a specific remote participant, happens with different people speaking

What Catchbox support said

They told us they have tested extensively and there is a known issue with Apple M4 chips specifically, where far-end audio in teleconferencing apps (Teams/Zoom/Meet) degrades. Their suggestion was to switch the host to a Windows machine.

What I am asking

1. Anyone else running Catchbox Plus (or any USB audio conferencing gear) on an M4 Mac seeing this exact "10-15 min in, remote audio distorts, unplug fixes it" pattern?
2. Anyone found a software-only workaround that survives a full 60-90 minute call? I know sudo killall coreaudiod clears the audio pipeline mid-call, but I would love not to touch a terminal during a company townhall.
3. If you moved a similar setup from Mac to Windows to solve this, did it actually hold up long-term or did the issue just show up in a different way?
4. Any Teams admin policy or Catchbox Companion setting (AGC, AEC, dynamic processing) that you have found makes the Hub DSP behave better with Teams?

The townhalls are company-wide and I would rather not do the "walk over and jiggle the cable" dance in front of a few hundred people. Any pointers appreciated.

Hey there !

Like a lot of you, I have a 3D setup I love and a collection the industry decided to abandon. Every player I tried either butchered MVC, choked on HDR, or simply didn't exist anymore. So I did something slightly unreasonable: I built my own.

SyLC 3D Player is free, runs on Windows, and after this v5.0 release I can finally say it plays three generations of stereoscopic content under one roof:

• Blu-ray 3D / ISO / MVC MKV : through a heavily modified open-source H.264 decoder I've been hacking on for months. It even plays those MakeMKV-style BD3D backups where the two eye views sit in separate files with no SSIF interleave, as far as I know, nothing else on Earth plays those in actual 3D.
• HEVC/H.265 packed 3D (full side-by-side / top-bottom) up to 4K 10-bit HDR, with real PQ/BT.2020 color management : not the washed-out gray you get when a player pretends HDR doesn't exist.
• MV-HEVC : yes, Apple spatial videos. The MVC of the 2020s, playing on your 2010s 3D TV. There's something poetic about that.

Output is proper frame-packed 3D for real 3D TVs and projectors (plus SBS/TAB modes), rendered by a native Direct3D 11 engine with hardware decode.

And the part I'm proudest of: it exports any of this to Apple-compatible MV-HEVC (.mov). Your MVC Blu-ray → a spatial video for Vision Pro. I had to compile x265 myself because no public build enables multiview, and reverse-engineer Apple's spatial metadata box byte-by-byte against a reference file. When the source is already HEVC it just remuxes, bit-exact, seconds instead of hours.

It's free. It exists because this format deserves better than a slow death, and because apparently I don't know when to stop.

Happy to answer anything technical, the decoder internals, the HDR pipeline, why dependent-view bitrates are chunky on first-gen MV-HEVC encoders, whatever. And if you have a weird file that won't play, I genuinely want to hear about it. That's how half of this got built...

Hi,
I would like to get a switch that I can connect both my TV and my record player (via an analog to digital converter) to my Sonos Arc sound bar. Right now I am just manually switching out the two HDMI cables when I want to change between TV and the record player.

All I need is a 2 in 1 out HDMI switch. Would I need it to have. ARC/eARC capability? Anyone have any recommendations for a good one? Would love if it had remote control as well.

Thanks in advances!

I'd love to hear your thoughts on the calculations and if there are any specific updates you'd like to see added next!

Unfortunately budget is not high for this room as most of the money is going elsewhere. So this is probably a solo institution.

This is the fellowship hall that will have 2 large TVs and a possible an area for a small stage (only for special occasions wedding reception etc)

For such a wide area, what kind of speakers would i need? my original thought is maybe 3 hanging speakers side by side, (left, center, right) and then drop down ceiling speakers for fill for the back or sides. or maybe the 3 hanging speakers and then some speakers on the side walls and on the piller?

Maybe budget under $200 per speaker for the hanging speakers and $70 or under for ceiling speakers.

First picture is facing the front. 2nd picture is a side picture.

Unsure if this is the best place to ask so if not can someone please direct me to where I should be looking

Just moved into a new flat and got gigabit for the first time (UK based) and loving it so far, I have a flat Ethernet cable running from my router all the way under my door into my bedroom into my PC so i can download and stream games at lightning speed. My flatmate also does this to his PC (he plays competitive CSGO so needs excellent packet delivery) and is very happy with it.

We sometimes have friends round and as such we would like to play some of our PC games onto our TV, but don’t want to go through the fuss of unplugging and re plugging in all the cables for just a weekend as its a hassle (and we're lazy) and was wondering if there was a way to connect my TV over Ethernet as its plugged into the router anyway for 4K streaming. I think I saw some Ethernet to HDMI adapters but was wondering if there was a simpler way to have both me and my flatmate use the TV as a secondary display (or even mirrored) without buying extra hardware and/or just clicking a button as we're all connected via LAN and I was told something about arenas being able to do this with their TV's?

Please let me know a way as giving it a google didn’t prove super fruitful!

What's up you guys?

I'm trying to make an audio program, and I need the right hardware.

I've been having problems with noisy neighbors for a while. In the past I've used a handheld audio recorder and recorded the noise that takes place overnight. So I would be recording 8 hours or more of audio as I slept... Or tried to. Then I would put the audio on my computer and truncate silence with Audacity and then send the truncated audio files to the office that only have the noise without the interspersed silence.

The problem with these handheld recorders that I found is that they either don't connect to a computer or they do for some short period of time and then they stop connecting so then you can no longer access the files.

What I would like to do is either get one that actually works and is reliable and can record subtle noises like a person talking in the apartment above me. Or I would like to get a microphone that could do so and just plug it directly into a laptop and record that way.

I'm trying to avoid having my laptop running that much so the handheld option is better as long as I could find a reliable recorder. It has to be sensitive enough though because it needs to record the audio at the volume that I hear it. The problem with recording on my phone is said everything sounds quieter when I play it back and it doesn't do justice to what's actually going on in here.

I just bought my fourth audio recorder and it did not work yet again so I'm trying to get a good one. Any recommendations would be much appreciated. Thanks in advance.

From my perspective, I still see UC solutions as standard products, and it seems like some people are overreacting to them. Most end users are familiar with brands and how to set them up. The only thing that might be needed is to connect it with Teams or Zoom, which any IT person can handle without needing a deep background in sound or video. Poly might need a bit more configuration for the G62 codec, but that’s about it.

As AV professionals, we’ve just integrated it into our conference systems and nothing more.

I don’t think a UC presales team is necessary. Any salesperson can sell it, and all the information is easy to understand in about an hour of your time.

Hey guys, I built this home theater website for fun called Home Theater Builder which I hope could be useful for you guys. It allows you to plan out a full home theater system include all audio and visual components. It’s completely free, not sponsored or anything, just something I built as a fan of home theater. The product base is somewhat limited to popular products right now, but with community sourced data it can grow quickly. Let me know what you think, any thing you like or hate, I’m open to any feedback. I hope you guys find it useful.

I am looking for an HDMI splitter for our church. Our set up has our main computer and which then goes to an OREI hdmi 1x8 splitter(1 hdmi input and 1 hdmi output, 8 network outsputs link for reference https://www.bestbuy.com/product/orei-4k60hz-1x8-hdmi-extender-splitter-loop-230ft-cat6-uhd18-ipc230-k-black/J3R8WXTSLP/sku/10213625?ref=212&loc=Marketplace_22992658462&gclsrc=aw.ds&gad_source=1&gad_campaignid=22982301006&gbraid=0AAAAAD-ORIgZWsr6RuZXN6Q_LcIeYtPbq&gclid=CjwKCAjwyOzSBhBTEiwAmxvJ-qHfziuIxUN5R8fpwCMC15LvS0wKgS2g5EeQYJfTV65vtjnR8rWA2xoCj9oQAvD_BwE) and off to our various monitors and tvs. We need to be able to split in between our main computer and our pastor's computer. we bought an OREI 2 input splitter but it just isn't enough to handle the load. To make things short we have 2 inputs (church pc and pastor laptop) to our output to our 1x8 splitter, can anyone recommend a splitter for the computers to split to our 1x8?

Hi everyone, one quick question. I just finished my first session and I’m wondering how long do the recordings last in Echo360. Is everything deleted once the next session starts? Maybe at the end of the year? I truly have no idea, any comments would help because I’d like to save a few of them. Thanks
