All controllers of USB audio devices come to be able to control through FreeBSD sysctl knob. http://sobarally.dyndns.org/~trench/uaudio/uaudio-mixer-sysctl.gz For example, when SB Digital Music and SB Live! 24-bit External are connected after applying the patch above, sysctl says: hw.snd.pcm0.record@sel8-i10i11i12: 1 hw.snd.pcm0.outputs@speaker-mute: 0 hw.snd.pcm0.outputs@speaker: 7474 hw.snd.pcm0.record@mic-mute: 0 hw.snd.pcm0.record@mic: 26976600 hw.snd.pcm0.record@mic-agc: 0 hw.snd.pcm0.record@line-mute: 0 hw.snd.pcm0.record@line: 7474 hw.snd.pcm0.record@aux-mute: 0 hw.snd.pcm0.inputs@mic-mute: 0 hw.snd.pcm0.inputs@mic: 7400 hw.snd.pcm0.inputs@line-mute: 1 hw.snd.pcm0.inputs@line: 7474 hw.snd.pcm1.outputs@speaker-mute: 0 hw.snd.pcm1.outputs@speaker: 7400 hw.snd.pcm1.record@line: 7700 `*@*-mute's are mute controllers. 0 is OFF and 1 is ON. `*@sel*-*' is a source selector. each `i[num]' corresponds to each input source. `hw.snd.pcm0.record@sel8-i10i11i12' shows three input source, and we can select them by 1,2 or 3. Almost others are volumes. first two orders correspond to a left or mono's volume. last two orders correspond to a right volume. their values are from 0 to 99. `hw.snd.pcm0.record@mic: 26976600' is ...... a bug, I'll research sometime. `sysctl -w' changes behaviors of the USB audio device, but this isn't reflected by FreeBSD mixer command.
