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:

My alsa config is here:

Any ideas?
Update 1
Also, dmesg produces:

Is there anyway to give it more generic parameters?
Update 2
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 messages. Is there anything I can do about the hw parameters?
