i also tried to build alsa but still the same problem as before: can't control
the volume or mute the sound
in gutsy all i had to do is put "options snd-hda-intel model=auto" in
/etc/modprobe.d/alsa-base [and still had only PCM volume in mixer; Master was
missing, but the sound worked well]
a) in gnome the mixer defaults to "Realtek ALC861 (OSS Mixer)" device and lists
3 pairs of sliders: 1) Volume, 2) Microphone, 3) CD; here comes the problem i
already mentioned: can't control the volume [the Volume slider(s) will jump to
max everytime i try to lower them] or mute the sound
b) if i switch to the next audio device ["Playback: ALSA PCM on front:0 (ALC861
Analog) via DMA (PulseAudio Mixer)"] i only get one twin slider: Master; this
one seems to work [i can get the output volume lower/higher and also mute it];
the thing is.. i should have at least: one Master, one PCM, one Microphone, one
CD [..] slider pairs [pairs as they are two for each channel: left & right];
another problem with this one: if i lower the volume down the next time i
reboot the welcome/login sounds will have the volume set to loudest [even if i
used to set this one -=Master=- down before restart]
c) the next device is "Capture: Monitor Source of ALSA PCM on front:0 (ALC861
Analog) via DMA (PulseAudio Mixer); obviously this one has nothing to do with
play [but recording]; i get only one slider pair (Master) and a microphone knob
[besides the mute one]; the mixer's tab is named Recording, so this Master
reffers to recording not playing
d) the fourth device is "Capture: ALSA PCM on front:0 (ALC861 Analog) via DMA
(PulseAudio Mixer)", and has only one master slider pair and that microphone
knob like the previous device [c)]
a temporary "fix" is to set the gnome mixer to the second device [as
described at b)], but this doesn't solve the problem
