OK. So, more generaly speaking, how do I send a 24 bit PCM file to 'any' 24 bit sound card. Any tools, demos, examples, etc? How do I get the capabilies of a sound card. (I checked /proc/asound/ but haven't found anything thats says "I can play 16bit, 8bit, ulaw,....") > There is a register bit which seems to toggle this, but as far as I've > tested it didn't work, thus disabled so far. > Please check card-cmipci.c. Ahh, I see, you mean CM_SPD24SEL, I guess. So, how do I enable it? There are no comments in the source that 24 bit output is disabled. In snd_cmipci_playback_spdif_prepare() it looks like that CM_SPD24SEL is allready used!? I've a simple S/P DIF test-setup available and some spare time left...
