Re: [alsa-devel] Is there a way to figure out if the clocks of two snd_pcm_t's deviate? (snd_pcm_info_get_sync?)

All standard soundcards have only one clock source, so if snd_pcm_info_get_card() number matches, the streams will most probably run in sync.

Hmm, does this also mean that SPDIF output and analog output of the same sound card stay in sync on most cards?

I would suggest to match card number as default for used streams and add an user option to modify the stream word clock configuration for your app.

OK, sounds good.
