Audio/Sound fails in macOS Catalina

I'm having trouble with the audio/sound after installing Catalina in my MacBook Pro (15-inch, 2016).

Sometimes the audio is gone and only come back if i restart the computer.

Even if i close the apps (including Music app) and reopen them again, there is no sound. Must restart the computer for the audio to come back.

This worked for me. Applications > Utilities > Activity Monitor. Under the CPU tab find (or search for) coreaudiod. Select it and then click the Stop button in the toolbar. When prompted, click Quit. This will restart the coreaudiod process and may bring your audio back.

I have the same problem on Catalina. I have a Macbook Pro 16" (brand new, but also happened on my previous macbook pro after upgrading to Catalina). For me, this issue occurs with my Bose USB audio system and Apple Music.


1) Play Music

2) Pause track

3) Start track again - no sound.


What I have to do all the time is unplug and re-plug in the Bose USB audio. When I unplug the Bose USB audio, the song is playing through the next audio device (usually my displays plugged in via USB C). After reconnecting the Bose USB audio, the audio switches back over to the Bose and plays normally.


Is this a problem with older USB devices? I'm using a dongle to connect the older USB to USB-C port.

Strangely, in the logs the audio failures that can be fixed by restarting coreaudiod always coincide with a series of ASL log messages, with a format like:


"25 Apr 2020 at 02:04:05 coreaudiod[209]: BUG in libdispatch: 19E287 - 2914 - 0x4"


When the speaker icon on the bar starts "blinking" (like going on and off), I found stuff like this:

Same issue. I have the blackmagic external gpu which connects to my monitor. The monitor has a sound out that I use to drive speakers. When connected the sound output device is LG HDR WQHD. If I leave the laptop for any length of time such that it sleeps then when I come back I still have video to the monitor, but the sound output is coming out of the laptop (clamshelled in a stand). The audio device for the monitor doesn't show up in output devices. I have to click to disconnect from the GPU (and monitor), open the laptop (so I can see), then unplug the usb-c that goes to the blackmagic and plug it back it. Then it re-connects to the blackmagic, the sound output device shows up, and sound starts coming back out of the speakers that are connected to the monitor. So, it seems Catalina has an issue with going into sleep or power saving and preserving sound devices.

Evening all,


So I've got similar issues but not as drastic as a lot of you...


I'm on a MacBook Pro 13" 2015 (3.1Ghz/16GB/512SSD) running 10.15.5


I'm a live sound engineer, so while I say my issues aren't as bad as others as the sound always returns, they can still be pretty bad and show stopping for me...


1) Audio Controls Freezing

This *seems* to be limited to when using an external soundcard, but I may be wrong... it just hasn't happened when using the minijack output yet... So... When using the volume up and down buttons slowly, or fast, the system can *hang* and either;

A - Mute playback and pause / freeze whatever video may be playing until it realises where the volume should be and then unmute at the volume level and the video then catches up fast forwarding to then be in sync

B - While it is working out what volume level it needs to go too, it continues to play the last 1 bar ish of music over and over and over on top of itself then jumps to the right volume and carries on - SUPER annoying...

It's got the the point now where it is that regular that the volume freezes that I don't even touch the controls and I use the volume knob on the audio interface I'm using - very annoying!


2) Audio Muting

Now, this one is more worrying but similar to what other people here have been experiencing

The Mac can be playing audio from anywhere, YouTube, Music App, Logic, Final Cut, Safari and just randomly mutes the output completely for around 2-5 seconds... then the audio returns, as if nothing happened...


In terms of programs I've got installed that others have mentioned;

  • Clean My Mac X - But I've had this YEARS so really doubt it is anything to do with that...
  • Parallels - This was installed recently but again, the problems happened way before that, all with Caralina, which was a completely fresh install too.


As others have said, if it's having big issues (but be aware in mine my audio always does come back so it's normally not enough time to open Activity monitor and restart core audio, or worth it etc) restarting core audio if you catch it quick enough does work. So does restarting and resetting the PRAM.


Just such an odd chain of events and makes the Mac not *good/safe* enough for live performances, or relying on even for video conferences... Glad I haven't updated the rest of them at work yet!


Luckily at the moment due to Coronavirus, this Mac isn't on live work. It's all studio based. but not ideal!!


The issue (ignoring the control ones as I don't touch them now) seems to happened not all the time too, can work fine for HOURS of a recording / mix session, not even do it once... But then later watching Netflix / Youtube it happens... so odd... (it has happened once when recording so Logic isn't exempt FYI too)...


Last thing to note is the Mac is setup permanently at the moment and never off, "prevent computer from sleeping when display is off" is selected, ie, the computer never sleeps, the screen goes off after like 3 hrs, if it did sleep then I might run into more issues like *having* to restart core audio or the Mac due to it properly going...


Very frustrating!


Any help / tips greatly received!


Cheers,

Chris
