You could try specifying your device as 'plughw:1'. From the ALSA 0.9.0
The most important ALSA interfaces to the PCM devices are the
"plughw" and the "hw" interface. If you use the "plughw"
interface, you need not care much about the sound hardware. If
your soundcard does not support the sample rate or sample format
you specify, your data will be automatically converted. This
also applies to the access type and the number of channels. With
the "hw" interface, you have to check whether your hardware
supports the configuration you would like to use.
The libasound reference goes into more detail:
The plughw device description uses the plug plugin and hw plugin
as slave. The arguments are same as for hw device.
