I am new to alsa development and I am in the midst of trying to debug the sound on my Toshiba Satellite u205 (no sound of the speakers, very very quiet sound of the headphone jack- it is an AD1981 chipset). My initial assumption is that the internal amplifier is not kicking in to boost the sound. So I have been reading the source code for the HP nx6320 patch to understand ALSA better and I was wondering if anyone would know if I could find the whitepaper for the chipset that the nx6320 uses (so i can figure out why certain structures are coded the way they are).
So far I have tried to define new volume and mute definitions in the snd_kcontrol_new ad1981_mixers[] ranging from 0x00 to 0x15 to "guess and check" if i can some how raise the volume or unmute the amplifier out. However there is something wrong with this approach that is not working and I am not familiar with alsa enough to figure out why :).
Attached is the results of #cat /proc/asound/card0/codec#0 for my codec, if anyone has any hints as to how to proceed please let me know!
