I guess my question is: what is the current > state of sound support in Paul's 2.3.52 kernel? My primary distribution source is also LimuxPPC. Geert Uytterhoeven posted a patch to split the DMA sound support between Pmac, Atari etc. a while ago (look for dmasound split). If you can't find it, I have a copy of the URLs to fetch it, somewhere. It works against 2.3.52 [Paul's tree] (with a small additional mod to drivers/char/mem.c) With the patch, 44.1k wav files >/dev/dsp work on G3(beige Minitower) & G3 Lombard + possibly some others... I am still trying to get to the bottom of why it doesn't on a 9600 [>50% chance that it's an unrelated problem] and checking out other formats. I haven't tried very hard to do anything without the patch. Theme Sound under KDE (1.1.1) seems to be broken with or without the patch (apart from Beep) - but that's probably a 2.3.xx issue. As for other issues e.g. whether OSS stuff works - well I never got the sequencer to work yet [under 2.2.6-apmac15, 2.2.14p9 or 2.3.xx] (but I didn't try very hard yet ;-) Once I understand the issues better I am going to try an ALSA driver for the pmac built-in sound (it might help you because ALSA has support for the 'legacy' sound methods - which might bring more of the x86 stuff into view). P.S. I'm pretty new to this particular kernel... so there's probably loads more to add. ciao, Iain. ** Sent via the linuxppc-dev mail list. See http://lists.linuxppc.org/
