so far, so good. > Oct 11 13:36:49 atrophy kernel: ALSA ../alsa-kernel/usb/usbaudio.c:1820: 4:2:1: add >audio endpoint 0x86 > Oct 11 13:36:49 atrophy kernel: ALSA ../alsa-kernel/usb/usbaudio.c:1820: 4:2:2: add >audio endpoint 0x86 > Oct 11 13:36:49 atrophy kernel: ALSA ../alsa-kernel/usb/usbaudio.c:1820: 4:2:3: add >audio endpoint 0x86 > Oct 11 13:36:49 atrophy kernel: ALSA ../alsa-kernel/usb/usbaudio.c:1820: 4:2:4: add >audio endpoint 0x86 > Oct 11 13:36:49 atrophy kernel: ALSA ../alsa-kernel/usb/usbaudio.c:1820: 4:2:5: add >audio endpoint 0x86 > Oct 11 13:36:49 atrophy kernel: ALSA ../alsa-kernel/usb/usbaudio.c:1601: 4:3:1 : >format type 2 is not supported yet > Oct 11 13:36:49 atrophy kernel: ALSA ../alsa-kernel/usb/usbaudio.c:1601: 4:3:2 : >format type 3 is not supported yet hmm, i didn't see any interface 2 or 3 in your lsusb output. could you try again "lsusb -v" so that we can check these interfaces? perhaps they correspond to SPDIF digital i/o. (these format types are not supported anyway, but it's possible to add such funcitionality.) > Oct 11 13:36:49 atrophy kernel: ALSA ../alsa-kernel/usb/usbmixer.c:808: [2] FU [PCM >Playback Switch] ch = 1, val = 0/1 (ship) there was a bug in for getting min/max values of the process-unit and extension-unit. it's fixed on cvs, so please try to update. > > > also, please check /proc/asound/card0/stream* files again. > > now there should be more entries in them (is it only one?). > > There is only one: > > atrophy:/proc/asound/card1# more stream0 > Creative Technology Ltd. : USB Audio > > Playback: (ship) strangely, there are some duplicated entires, i.e. the same format, the same channels and the same rate. in fact they appear in the usb descriptors. i don't know what is difference. anyway, i'm looking forward to further your results. ciao, Takashi ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
