Happened again today. Here are the logs. The event was around 9:13.

I was updating some apps when the phone rang. At the second call (around 9:14) 
all went OK.

I have updated to 7.2.0 RC0a before the calls.

PS: I have a custom ring tone for that caller.

Thanks for the logs. Unfortunately, I can't find anything going wrong there... 

I'll repeat here what I posted at #755 so it's more visible:

As I said elsewhere, I'm not able to reproduce this issue, which is rather 
unfortunate.
If this issue would be specific to 7.2 RC builds, then there would be an 
obvious suspect - the updated libaudio.so that enables call recording.
But if the issue appears already in 7.1.5, then it has to be caused by 
something else...

Anyway, as a first take on this issue, I attach an update package for 
OpenRecovery that will revert the libaudio.

Please let me know if it makes any difference.

I can imagine other possible causes of this issue, so lets test them one after 
another :) .
Just one additional question for now: does it happen mainly for some particular 
contacts? Especially the ones that are using some specific ringtone?

It happened with other contacts also. I'll install the downgrade of libaudio 
and see if this repeats.

I am suspecting the call recording feature (actually, an initialization in that 
library).

Had the same problem, I am on a Latam xt720 with CM 7.2.0 RC1 and came from a 
stock 2.2 rom, I applied the libaudio update kabal provided and have been 
receiving calls normally today.

No audio problems since downgrading libaudio 

Original comment by justc...@gmail.com on 23 Apr 2012 at 5:55

[GoogleCodeExporter]

I updated to 7.2.0-RC1 + reverting libaudio. 
And for me still no solution for the issue.

Please help.

Hi Pavel,

I have been on 7.2RC1 and am enjoying an advanced, if aging, phone. My info: I 
also had those 'mute calls' but my workaround was to press the 'hold' and then 
'unhold' - then the call was OK.

I've included a possible workaround in CM 7.2.0 RC2.
Please let me know if you still experience this issue when running RC2.

Thanks for the reports. I hope that this patch will finally fix it for good:

976e15936e6cf9136ca9782

Btw., has any one from you who encounter this issue frequently set the 
ro.telephony.call_ring.delay to some low value? Because that would cause higher 
probability of this bug manifestation.

I never changed that value and it happens very often (2 out of 5 or something).

I'll try that new build and I'll keep you posted.

No problems so far.

As the fix is based on careful second inspection of the provided logs (I didn't 
spot it the first time I checked them - it was not that easy to get what is 
going on), I'm pretty sure the issue is indeed finally fixed.
Thanks for the feedback and the logs.
