Here are some more:

Echo - #1267

GSM buzzing - #883 #1352 (and maybe #938 )

Adding "blocked by" the bugs will mentioned.

[hedora]

Does "audio" mean "during calls", or in general? There are a few volume setting and mediaplayer bugs that are related to audio... What about gstreamer/pulseaudio bugs?

Tell me to and I'll go track them down.

[jurg]

for the echo (buzzing appeared to be less as well) i tweaked the alsa settings. the resulting scenario's are attached and work for me (my friends 'on the other end' are not complaining anymore.) (only gsmhandset is changed, i think.)

[Treviño]

I would also add:

• Low ringtone volume
• Low Speakerphone volume

[liedekef]

I can confirm the echo and buzzing issue with the release Om2008.8-gta02-20080903.uImage.bin and Om2008.8-gta02-20080904.rootfs.jffs2. I can also confirm that the scenarios added by jurg fix this issue.

We have something to take a look at, set HasPatch?.

@graeme: The bug is assigned to you, if you don't think this is appropriate talk with someone about it.

[Treviño]

Well, in my device, using the jurg's scenarios I've a really low volume...

[graeme]

Testing these is a problem for me, I find it difficult to get far enough away from myself to phone myself without feedback.

[liedekef]

Replying to Treviño:

Well, in my device, using the jurg's scenarios I've a really low volume...

True, I just discovered this as well. Incresing one of the playback parameters fixes this, but then the feedback might return ...
