Hi Clemens, to be honest, this is the first time ever I am trying to use TOS an a card, so I have no idea. The result: $ amixer contents -c 1 numid=2,iface=MIXER,name='Master Playback Switch' ; type=BOOLEAN,access=rw------,values=1 : values=on numid=1,iface=MIXER,name='Master Playback Volume' ; type=INTEGER,access=rw---R--,values=2,min=135,max=255,step=0 : values=250,250 | dBscale-min=-60.00dB,step=0.50dB,mute=0 numid=23,iface=MIXER,name='Headphones Impedance Playback Enum' ; type=ENUMERATED,access=rw------,values=1,items=3 ; Item #0 '< 64 ohms' ; Item #1 '64-300 ohms' ; Item #2 '300-600 ohms' : values=0 numid=19,iface=MIXER,name='Line Capture Switch' ; type=BOOLEAN,access=rw------,values=1 : values=off numid=17,iface=MIXER,name='Mic Boost (+20dB)' ; type=BOOLEAN,access=rw------,values=1 : values=off numid=18,iface=MIXER,name='Mic Source Capture Enum' ; type=ENUMERATED,access=rw------,values=1,items=2 ; Item #0 'Mic Jack' ; Item #1 'Front Panel' : values=0 numid=16,iface=MIXER,name='Mic Capture Switch' ; type=BOOLEAN,access=rw------,values=1 : values=off numid=15,iface=MIXER,name='Mic Capture Volume' ; type=INTEGER,access=rw---R--,values=1,min=0,max=31,step=0 : values=0 | dBscale-min=-34.50dB,step=1.50dB,mute=0 numid=21,iface=MIXER,name='Aux Capture Switch' ; type=BOOLEAN,access=rw------,values=1 : values=off numid=20,iface=MIXER,name='Aux Capture Volume' ; type=INTEGER,access=rw---R--,values=2,min=0,max=31,step=0 : values=0,0 | dBscale-min=-34.50dB,step=1.50dB,mute=0 numid=9,iface=MIXER,name='IEC958 Loopback Switch' ; type=BOOLEAN,access=rw------,values=1 : values=off numid=10,iface=MIXER,name='IEC958 Validity Check Capture Switch' ; type=BOOLEAN,access=rw------,values=1 : values=on numid=3,iface=MIXER,name='IEC958 Playback Switch' ; type=BOOLEAN,access=rw------,values=1 : values=off numid=11,iface=MIXER,name='Analog Input Monitor Playback Switch' ; type=BOOLEAN,access=rw------,values=1 : values=on numid=12,iface=MIXER,name='Analog Input Monitor Playback Volume' ; type=INTEGER,access=rw---R--,values=1,min=0,max=1,step=0 : values=1 | dBscale-min=-6.00dB,step=6.00dB,mute=0 numid=22,iface=MIXER,name='Analog Output' ; type=ENUMERATED,access=rw------,values=1,items=3 ; Item #0 'Speakers' ; Item #1 'Headphones' ; Item #2 'FP Headphones' : values=0 numid=24,iface=MIXER,name='DAC Filter Playback Enum' ; type=ENUMERATED,access=rw------,values=1,items=2 ; Item #0 'Sharp Roll-off' ; Item #1 'Slow Roll-off' : values=0 numid=13,iface=MIXER,name='Digital Input Monitor Playback Switch' ; type=BOOLEAN,access=rw------,values=1 : values=on numid=14,iface=MIXER,name='Digital Input Monitor Playback Volume' ; type=INTEGER,access=rw---R--,values=1,min=0,max=1,step=0 : values=1 | dBscale-min=-6.00dB,step=6.00dB,mute=0 numid=8,iface=PCM,name='IEC958 Capture Default',device=1 ; type=IEC958,access=r-------,values=1 : values=[AES0=0x00 AES1=0x00 AES2=0x00 AES3=0x00] numid=7,iface=PCM,name='IEC958 Capture Mask',device=1 ; type=IEC958,access=r-------,values=1 : values=[AES0=0xff AES1=0xff AES2=0xff AES3=0xff] numid=5,iface=PCM,name='IEC958 Playback Con Mask',device=1 ; type=IEC958,access=r-------,values=1 : values=[AES0=0x3e AES1=0xff AES2=0x00 AES3=0x00] numid=4,iface=PCM,name='IEC958 Playback Default',device=1 ; type=IEC958,access=rw------,values=1 : values=[AES0=0x04 AES1=0x82 AES2=0x00 AES3=0x00] best regards, Hendrik-Jan 2013/8/23 Clemens Ladisch <cladisch@xxxxxxxxxxxxxx>: > Hendrik-Jan Heins wrote: >> I have an issue getting the optical connection on the Asus Xonar STX >> working in my system. >> >> I can see the device, and the alsamixer is available.
