Hello, I am trying to get this card working. It seems Maya does not complain USB standard. The ALSA subsystem detect it, it wake up but the mixers are not configured properly (since this card has 2+2 stereo inputs/outputs). What to do? Do I have chances to get it working? Thanks for help ps - sorry for the long post, see the output of lsusb and the error message - what this does mean? teepee card1 # pwd /proc/asound/card1 teepee card1 # cat stream0 AUDIOTRAK MAYA44 USB at usb-0000:00:1d.1-2, full speed : USB Audio Playback: Status: Stop Interface 1 Altset 1 Format: S16_LE Channels: 4 Endpoint: 1 OUT (ADAPTIVE) Rates: 44100, 48000 Capture: Status: Stop Interface 2 Altset 1 Format: S16_LE Channels: 4 Endpoint: 2 IN (SYNC) Rates: 44100, 48000 alsaplayer -o alsa -d default=hw:1,0 test.mp3 ALSA lib pcm.c:2090:(snd_pcm_open_noupdate) Unknown PCM default=hw:1,0 snd_pcm_open: file not found (default=hw:1,0) Failed to initialize plugin! teepee card1 # amixer -c1 Simple mixer control 'Speaker',0 Capabilities: pvolume pswitch pswitch-joined Playback channels: Front Left - Front Right Limits: Playback 0 - 255 Front Left: Playback 207 [81%] [off] Front Right: Playback 207 [81%] [off] Simple mixer control 'Speaker',1 Capabilities: pvolume pswitch pswitch-joined Playback channels: Front Left - Front Right Limits: Playback 0 - 255 Front Left: Playback 211 [83%] [off] Front Right: Playback 211 [83%] [off] Simple mixer control 'Speaker',2 Capabilities: pvolume pswitch pswitch-joined Playback channels: Front Left - Front Right Limits: Playback 0 - 255 Front Left: Playback 230 [90%] [on] Front Right: Playback 230 [90%] [on] teepee card1 # amixer -c1 controls numid=1,iface=MIXER,name='Speaker Playback Switch' numid=3,iface=MIXER,name='Speaker Playback Switch',index=1 numid=5,iface=MIXER,name='Speaker Playback Switch',index=2 numid=2,iface=MIXER,name='Speaker Playback Volume' numid=4,iface=MIXER,name='Speaker Playback Volume',index=1 numid=6,iface=MIXER,name='Speaker Playback Volume',index=2 teepee card1 # amixer -c1 contents numid=1,iface=MIXER,name='Speaker Playback Switch' ; type=BOOLEAN,access=rw---,values=1 : values=off numid=3,iface=MIXER,name='Speaker Playback Switch',index=1 ; type=BOOLEAN,access=rw---,values=1 : values=off numid=5,iface=MIXER,name='Speaker Playback Switch',index=2 ; type=BOOLEAN,access=rw---,values=1 : values=on numid=2,iface=MIXER,name='Speaker Playback Volume' ; type=INTEGER,access=rw---,values=2,min=0,max=255,step=0 : values=207,207 numid=4,iface=MIXER,name='Speaker Playback Volume',index=1 ; type=INTEGER,access=rw---,values=2,min=0,max=255,step=0 : values=211,211 numid=6,iface=MIXER,name='Speaker Playback Volume',index=2 ; type=INTEGER,access=rw---,values=2,min=0,max=255,step=0 Bus 002 Device 004: ID 0a92:0091 EGO SYStems, Inc.
