Over the last couple weeks, there has been a growing problem with my audio output. Lately, especially after sitting idle overnight or even several minutes, Avid will intermittently only play out my left channel of audio. It then finally snaps out of it after a few seconds or minutes - often during the playout. Another symptom being that three times now, I've played a sequence and the audio repeats a 1 second or so portion during playout causing everything to play out of sync. 

Early on I thought it was my audio mixer hardware before other symptoms began.

Does this sound like an Avid issue? AJA IO Express issue? or perhaps a drive (SAN) issue?

Thanks in advance.

Hi Jonathan,

Have you been able to get any further with your audio problem? I'm also having a customer with similar problems; after the system has been idle lots of times the audio playback will become muffled and very low volume. This can only be solved by restarting Media Composer. This system is also using a Io Express and MC 8.2 so they are somewhat similar (other specs: Z440, 32GB RAM, Win 8.1 x64).

Interesting. No suggestions yet. The only thing I haven't done yet is upgrade to 8.3 from 8.2. 

Matrox works brilliant here on Pc so that might point towards Aja , maybe try different drivers

I have tried to upgrade from 8.2 to 8.3 and also installed the latest AJA drivers (new unified driver release) but seems not to have helped... Also double checked everything was setup per Avid's Z440 config guide. Disabled Win8 fast start. But it still is happening my customer is telling me :-(  (of course it doesn't happen when i'm onsite)

FWIW you used to get something like this happen with the Digi IO settings on a Mac. Deleteing the preferences and letting Avid rebuild them would solve it.

It MAY be worth going through and rebuilding all the settings. See Randall's post here

I assume the audio VU meters indicate volume? or are they flat?

I'll play around with the user profiles and look at other suggestions. 

Yep, VU meters look just fine throughout.
