I was playing with the alsa source in kernel-2.6.0 and after "fixing" a few
things, my Line-In2 started working as expected.
This is my testing procedure:
- Headset plugged in the Headphones and Mic of the LiveDrive. Card is Live
Platinum (with the IEEE1394).
- Unload all alsa modules and confirm nothing is loaded.... cat
/proc/asound/cards says "no cards". My sound-related modules are compiled in
the kernel and only the card-specific drivers are modules.
- modprobe snd-emu10k1
- set a few volume levels (all are default, module is freshly loaded and
alsactl is not used). I set the headphones, so I can be more than sure that I
do not record what I am hearing. The names do not correspond to the original
ones, because of the changes to the source.
amixer cset numid=36,iface=MIXER,name='Headphone Playback Volume',index=1 50,50
amixer cset numid=24,iface=MIXER,name='LiveDrive Line1 Capture Volume' 100,100
amixer cset numid=25,iface=MIXER,name='LiveDrive Line1 Capture Switch' on,on
In reality I used alsamixer to set these three values, but for clarity I show
the amixer commands here.
- Test recording
arecord -f cd > out.wav
aplay out.wav
Works fine and nothing was heard while recording. AC97 capture level is down,
Capture switch is off etc.
The exact same procedure does not work using the original sources.
I attach my patch, but it is already too late (it is MORNING already) for me to
check what exactly "fixed" the problem. The reason I started playing with the
sources, was because gamix had trouble identifying some of the controls, so I
decided to change the names to more reasonable values. I also removed the
indexing of the "LiveDrive Line" controls and it suddenly worked as if by
magic. I hope some guru creates a more reasonable patch.
One more thing. Happy New Year! I hope this patch makes a bunch of us happy,
even in its present very ugly state.
