librespot not open device correctly

[yejun]

It seems librespot does not use correct sample rate with my USB dac. When I run librespot manually from command line with --device plughw:1, sample rate is set correctly.

Possible to add an option for plughw?

Code:

Thats interesting. I thought librespot only accepted the device name.

plughw could be used universally. I'll do some testing.
