48. The advice on the wiki is bad, and likely to lead to distortion. Keep 48 low unless you have 12 and 5 near maximum. > Does anything change in the mike when going from handset to speakerset? Possibly, especially if you've changed the mic settings in gsmhandset.state. 48, 12 and 5 are the channels you want to look at for the mic. > The page on the wiki isn't very enlightening for non-handset cases... Half of me thinks this is a good idea as if it's not obvious from the diagram at http://wiki.openmoko.org/wiki/Neo_1973_audio_subsystem#ALSA_Channels then people are probably going to combine the settings badly anyway. The other half says I want to check through all the state files anyway, and I may as well document it better when I do. If you're using an FSO-based distro you could try fso-simplemixer.py. It presents you with a single slider for Mic, and sets the required channels in a sensible combination. The few reports so far suggest it does a good job, but back up your state files or using it just in case. Details in the thread below. http://lists.openmoko.org/pipermail/community/2009-October/056063.html > Rui > > On Thu, Oct 29, 2009 at 04:16:37PM +0800, William Kenworthy wrote: > > This sounds something like others experienced after changes to the > > default shr alsa file - Try turning the Mike gain down a bit - it could > > be overdriving (symptoms for me were fait audio, cracles and rushing > > sounds like wind, but distant sounds came through clearly - if there was > > ambient noise the FR was unusable).
