Hi,
I have given another go to fix Gravis Ultrasound configuration for ALSA and I have found a working configuration. The Gravis Classic card uses non-mmap and non-interleaved sound format so aplay fails with standard configuration. Even worse, no default pcm device is defined so someone who wants just install Linux on old computer won't get any sound.
I have modified the GUS.conf from the /usr/share/alsa/cards and the GUS card now works with alsa and oss. My changes to the GUS.conf are below (as a diff).
Does anybody know how to upload MIDI instruments into the GUS card under ALSA? (like with awesfx for SB AWE)
I think some of the related code was never brought over from the ultra sound project driver. MIDI emulation is at least missing. There was/is some support for loading at least simple instruments (eg. mod samples). I was trying to get mikmod to work with ALSA sequencer + GUS PNP at some point. I managed to get decent playback but I never got the timing related stuff working correctly. That was many years ago though. At the moment all of my GUS cards are gathering dust on the shelf but if you're going to hack around with this stuff I can at least volunteer as a tester.
My mikmod patch is still @ http://www.sci.fi/~syrjala/alsa/
