SB Live! Platinum CT4760P is just a 4 channels sound card with STAC9721 and
Philips UDA1334 DAC
Is it feasible to remove "Center" , "LFE", "Wave Cetner" and "Wave LFE"
Playback Volume control ?
or add a bitmap to disable the creation of those controls
Anyone know whether this patch has any side effect for the user with Live
AFAIK, speaker-test will fail
speaker-test -d -c 6 -t wav -Dsurround51:1
Playback device is surround51:1
Stream parameters are 48000Hz, S16_LE, 6 channels
ALSA lib setup.c:565:(add_elem) Cannot obtain info for CTL elem
(MIXER,'Headphone Center Playback Switch',1,0,0): No such file or directory
Playback open error: -2,No such file or directory
