The VideoLAN Forums

Ok, this is an old problem but I have a new twist. Many of us know about the issue with apps like VLC & Audacity changing the sound settings in AudioMidi Setup & it's relation to the loss of sound in quicktime & loosing the ability to play system sounds.

Used to be I could go into AudioMidi Setup & change it back after quitting VLC & all would be fine again. This still works with Audacity, but VLC no longer seems to change the settings there. What it is doing I don't exactly know because I am experiencing the same exact symptoms but AudioMidi doesn't recognize any changes having occured. Change the settings around in AudioMidi doesn't fix the issue either.

The known fixes reported for this originally were
- Open GarageBand
- Change AudioMidi Setup back to 44100Hz 16bit-2ch
- Fix Permissions

Nothing, I got some audio capability back in Quicktime but not all, doesn't seem to get back the ability to play surround sound formats.

From what I understand the issue used to come from VLC changing the format to 96000Hz & 32bit - 2ch (or something along those lines). This is outside of the capabilities of system applications that play sound.

I'm afraid I don't have enough skill to fully troublshoot this issue but I want to know if anyone else has seen this. I'm on a Core Duo 1 17" Intel iMac. I would appreciate any help I can get. Thanks.

Bump...

I'm seeing the same problems. Especially when VLC is playing an a52 audio file over an optical connection in the Mac.

Restart is required for me.

There is another way. Instead of restarting open up Activity Monitor & kill coreaudiod (running under root). Authenticate as root user, coreaudio will restart & you are back in biz. Make sure you have closed out your audio apps like iTunes, Quicktime, etc. before doing this. Saves you a full restart.
