> I don't know how to test it in a correct way. I don't know what hw:0,0
stands for in my case. So far I did:
speaker-test -c2 -t wav -d -D hw:0,0
hw:0,0 mean card 0 device 0
there are 32 subdevices for playback
APLAY
**** List of PLAYBACK Hardware Devices ****
card 0: Live [SB Live! Value [CT4832]], device 0: emu10k1 [ADC
Capture/Standard PCM Playback]
Subdevices: 32/32

> Seems to work ok with this test file and also when I press in settings
rear lef rear right but the problem is still no control for this in Master
and no sound from line in (TV tuner). The stange thing is that after I did
PulseAudio/Log test some new controls/sliders appeared in Kmix and I could
choose the main channel and there was option for wave surround and this
allowed me to control sound level from this one slider in kmix in tray.
Although I tried to chack many sliders Line in didn't worked.
Line in playback is provided by ac97 mixer which connect to green jack
only, you lost the wavetable synth, mic, line in, video playback of ac97
mixer if your green jack is broken
the black jack is connected to i2s dac

where basic channel is set to surround 4.0 and there are no other options.

aplay reports CT4832.
