Microphone gain on N900
Hi!
v4.10 works quite nicely on N900, but I still have problems with audio. Even GSM calls would be usable, if I had reasonable volume on microphone and speaker... but I don't.
Both speaker and microphone are too quiet. I can get louder output by plugging headset -- good. I can hear the other side nicely, but am too quiet for them. Unfortunately, even if I plug in wired headset, internal microphone is still used.
Now... I researched mixer settings in v4.4, v4.10 and v2.6.28... and could not find way to control microphone. v2.6.28 is completely different from the other two. v4.10 misses many controls from v4.4; and I guess this might be related:

Pali, do you have maemo running on top of recent kernel (v4.1, v4.4, v4.10?). Do voice calls work there?
Any ideas welcome...
Best regards,
Pavel

Jarkko, Peter: can you look at above errors? Looks like audio routing is not correctly configured.

Now I do not have prepared Maemo + mainline kernel for testing...
I remember that Maemo sscd/csd/... daemons were able to connect to cellular network but I was not trying to make voice calls.

For me these settings provide reasonable playback and capture volumes using v4.10.1:

This seems to correspond to volumes I have had before. They are enough for phone call in quiet environment, but not really for normal usage.
Do you have settings where microphone on wired headset works?
Thanks,
Pavel

Those settings above. They are set after putting all volumes to 0 and muted. I'm using the Nokia WH-205 headset that came with the phone.

I just wanted to say thank you. I finally got to testing those settings again, and this time headset microphone definitely works.
Loopback using arecord | aplay now produces reasonable volume of audio. (Unfortunately, I still have some problems somewhere in the audio<->GSM path :-( ).
