Hello, I have a sound card listed as Bus 002 Device 002: ID 0d8c:0102 C-Media Electronics, Inc. CM106 Like Sound Device . The card physically is this: http://www.buyincoins.com/new_en/details/usb-2-0-6-channel-7-1-external-audio-sound-card-s-pdif-product-724.html . The card mostly works - I can easily output to "FRONT OUT", "REAR OUT", "CEN/BASS OUT". And I can capture through "LINE IN". I am not interested in the rest of interfaces. One can see in the URL above that the mentioned interfaces are the only default playback interfaces, however, the card is shown as 7.1. so an 8 channel playback should be possible (I need the card for measurement purposes - not for 7.1 amplifier/speakers). Here is what 'amixer -c 2 contents' shows: " numid=14,iface=MIXER,name='PCM Capture Source' ; type=ENUMERATED,access=rw------,values=1,items=4 ; Item #0 'Mic' ; Item #1 'Line' ; Item #2 'IEC958 In' ; Item #3 'Mixer' : values=2 numid=12,iface=MIXER,name='PCM Capture Switch' ; type=BOOLEAN,access=rw------,values=1 : values=off numid=13,iface=MIXER,name='PCM Capture Volume' ; type=INTEGER,access=rw---R--,values=2,min=0,max=6928,step=0 : values=6928,6928 | dBscale-min=-16.00dB,step=0.00dB,mute=0 numid=3,iface=MIXER,name='Line Playback Switch' ; type=BOOLEAN,access=rw------,values=1 : values=on numid=4,iface=MIXER,name='Line Playback Volume' ; type=INTEGER,access=rw---R--,values=2,min=0,max=8065,step=0 : values=8065,8065 | dBscale-min=-24.00dB,step=0.00dB,mute=0 numid=9,iface=MIXER,name='Line Capture Switch' ; type=BOOLEAN,access=rw------,values=1 : values=off numid=10,iface=MIXER,name='Line Capture Volume' ; type=INTEGER,access=rw---R--,values=2,min=0,max=6928,step=0 : values=0,0 | dBscale-min=-16.00dB,step=0.00dB,mute=0 numid=1,iface=MIXER,name='Mic Playback Switch' ; type=BOOLEAN,access=rw------,values=1 : values=off numid=2,iface=MIXER,name='Mic Playback Volume' ; type=INTEGER,access=rw---R--,values=2,min=0,max=8065,step=0 : values=8065,8065 | dBscale-min=-24.00dB,step=0.00dB,mute=0 numid=7,iface=MIXER,name='Mic Capture Switch' ; type=BOOLEAN,access=rw------,values=1 : values=on numid=8,iface=MIXER,name='Mic Capture Volume' ; type=INTEGER,access=rw---R--,values=2,min=0,max=6928,step=0 : values=6928,6928 | dBscale-min=-16.00dB,step=0.00dB,mute=0 numid=11,iface=MIXER,name='IEC958 In Capture Switch' ; type=BOOLEAN,access=rw------,values=1 : values=off numid=5,iface=MIXER,name='Speaker Playback Switch' ; type=BOOLEAN,access=rw------,values=1 : values=on numid=6,iface=MIXER,name='Speaker Playback Volume' ; type=INTEGER,access=rw---R--,values=8,min=0,max=197,step=0 : values=197,197,197,197,197,197,197,197 | dBscale-min=-36.93dB,step=0.18dB,mute=0 sergei@amdam2:~> amixer -c 2 cset numid=4, sergei@amdam2:~> amixer -c 2 cset numid=4 8065 numid=4,iface=MIXER,name='Line Playback Volume' ; type=INTEGER,access=rw---R--,values=2,min=0,max=8065,step=0 : values=8065,8065 | dBscale-min=-24.00dB,step=0.00dB,mute=0 ". Even though I have: 1) numid=4,iface=MIXER,name='Line Playback Volume' ; type=INTEGER,access=rw---R--,values=2,min=0,max=8065,step=0 : values=8065,8065 2) numid=3,iface=MIXER,name='Line Playback Switch' ; type=BOOLEAN,access=rw------,values=1 : values=on , i.e. I think (wrongly ?) I've enabled playback through "Line", I hear nothing when headphones are plugged into line. Any ideas ?
