[alsa-devel] PCM Volume on FSC V5505
Hi ! With the patches, the sound works - well done! But I need to make sure the PCM volume is max @ 50% . If its over 50% sound is clipped and ugly (overload?).
Here's cat /proc/asound/card0/codec#0 when in use (patched kernel with your patches for v5505)

Looks like so. Mixer apps (e.g. alsamixer) can show its dB value instead of percent. Check the dB level shown there.
The patch below may fix this issue. Give it a try.

Argh, the patch is wrong. Use the below instead.

The levels were 0-43 on Master and PCM. When PCM was over 20 it sounded ugly. Your patch fixed it with PCM. Master now 0-43, PCM now 0-20 . What about the inputs are they affected before/after the patch ?
Many thanks !

In the recent version of alsamixer, you must be able to see the corresponding dB level. I guess it's 0dB.
Your patch fixed it with PCM. Master now 0-43, PCM now 0-20 . What about the inputs are they affected before/after the patch ?
Which inputs, more exactly?
