[linux-audio-user] usb audio

Hello, I have an up2date red hat 8.0 install with external usb audio device (extigy). I compiled, installed, and loaded alsa modules; the following issues are present: [root@drs0 alsa]# alsactl store alsactl: get_control:194: Cannot read control '2,0,0,Digital In Playback Source,0': Invalid argument [root@drs0 alsa]# play /usr/share/sounds/phone.wav sox: Unable to sync dsp [root@drs0 alsa]# amixer contents <snip> numid=3,iface=MIXER,name='Digital In Playback Source' ; type=ENUMERATED,access=rw---,values=1,items=2 ; Item #0 'PCM' ; Item #1 'Input 1' amixer: Control default element read error: Invalid argument numid=23,iface=MIXER,name='Digital In Playback Source',index=1 ; type=ENUMERATED,access=rw---,values=1,items=2 ; Item #0 'Mixer' ; Item #1 'PCM' amixer: Control default element read error: Invalid argument <snip> This appears to systemic problem May 7 16:00:52 drs0 kernel: ALSA ../alsa-kernel/usb/usbaudio.c:1869: 3:3:1 : format type 2 is not supported yet May 7 16:00:52 drs0 kernel: ALSA ../alsa-kernel/usb/usbaudio.c:2019: 3:3:1 : invalid FORMAT_TYPE desc May 7 16:00:52 drs0 kernel: ALSA ../alsa-kernel/usb/usbaudio.c:1869: 3:3:2 : format type 3 is not supported yet from an unsupported pcm type. has anyone worked around this?
