Re: [alsa-devel] Getting stable PCM device id

I wonder how to get a PCM identifier that would be stable if you reboot or plug/unplug sound cards in a random order.

I'm not an expert in hardware ids, yet I imagine that we could use the hardware serial number or equivalent?

The most detailed identification is likely to show up in the card's longname.
