still having trouble getting my xmos card to work, after updating to the latest kernel my card appeared as a snd-usb-audio device and is listed in aplay -l
I have set it to be the first card in options in alsa-base.conf
I have the following in asound.conf
pcm.!default { type hw card 0 } ctl.!default { type hw card 0 }
But it will not play audio
sudo aplay -D plughw:0,0 /media/Disk2/Rehab.flac [sudo] password for stu: Playing raw data '/media/Disk2/Rehab.flac' : Unsigned 8 bit, Rate 8000 Hz, Mono aplay: set_params:1297: Unable to install hw params: ACCESS: RW_INTERLEAVED FORMAT: U8 SUBFORMAT: STD SAMPLE_BITS: 8 FRAME_BITS: 8 CHANNELS: 1 RATE: 8000 PERIOD_TIME: 125000 PERIOD_SIZE: 1000 PERIOD_BYTES: 1000 PERIODS: 4 BUFFER_TIME: 500000 BUFFER_SIZE: NONE BUFFER_BYTES: 4000 TICK_TIME: 0
my alsa config is here:

any ideas?

also dmesg produces:

- is there anyway to give it more generic parameters?

Thanks, I've converted a file to 48Khz wav but still get errors:#
ALSA lib pcm_direct.c:998:(snd1_pcm_direct_initialize_slave) unable to install hw params ALSA lib pcm_dmix.c:1034:(snd_pcm_dmix_open) unable to initialize slave aplay: main:722: audio open error: Input/output error
I even ran a live cd with ubuntu desktop to make my life easier but alsa kept giving errors msgs, is there anything I can do about the hw parameters?
