[Pull Request] id add soundcard

[metasystem]

Hi, can't add pull requests (don't know why). Can you add the possibility to set card with alsa ident instead (or in addition to) card numbers. On multiple usb dac configuration, usb order may cause problems on alsa detect (they change every reboot). Alsa detect cards in usb discover order. So, numbers can't be used in some cases... If you can set this "issue" in request, it would be great... Thx.
