Greetings I also have that USB Sound thingy. It plays my sound, even in 5.1. But I only have PCM and Capture in alsamixer. Output of amixer controls: numid=1,iface=MIXER,name='PCM Playback Switch' numid=2,iface=MIXER,name='PCM Playback Volume' numid=3,iface=MIXER,name='PCM Capture Volume' I have surfed the net for some days now to find a solution. I know from lsusb that my card has audio controls for more than 2 streams + 1 switch. What I really miss is the opportunity to hear the sound of my tv via Line-In. I can capture the sound but it is not passed through to the speakers. I even checked the source of usbaudio.c - and found special routines for 2 other sb usb cards. Now I think there are 2 possibly solutions: a) we need a special bootup-code for the usb-card b) alsa or the usb-subsystem of the kernel do not use the correct usb-interface Anyway I suppose we need a patch to the source. Or is there anyone out there who can access more than 2 controls in alsamixer and alike? ------------------------------------------------------------------------- Take Surveys. Earn Cash.
