Dear All:
I got late Pd version running under RHat-LinunPPC 1999 on a Power Macintosh 9600/350, getting sound thorough the builtin card. Just wondering how could I make the digidesign 888 I/0 24 card also to work. Alsa/OSS do not seem to like it.
Cheers,
Ricardo

OS: LinuxPPC2000 for powermacs on a PPC 7200/90 Audio works fine in full duplex -r 22050 but MIDI doesn't work. Typing lsmod as root --> module : dmasound when starting up PD: 'midi error, continuing without'
just wondering how could I get midi to work.

I don't think anyone yet tackled MIDI on PowerPC Linux. I don't think there are any drivers (and OSS does not support it AFAIC). There are issues with the speed of the serial port on a mac so it's a matter of hacking up something, I guess, but what do I know....
However, I'm running LinuxPPC1999 and Guenter's version did not function (I posted a while ago about the problem with gui not talking with the rest...). However, I tried today Miller's version and it behaves nicely but no audio... ioctl reports a problem with OSS not being able to connect to device 0 ... All my OS has is the oss kernel module.
Any ideas?
I haven't been able to run any sound app other than mp3 players....
I remember someone posted some fix of the endianess problem (changing a line or 2 in the sources).
I'm on a ppc 7200/120
thnx

if you can run an mp3 player sound should be oke ? maybe just some device name stuff again or .. .. and the -frags/-fragsize options.
i m running miller's version on debianPPC on the imac. everything top so far except for midi () + endianess when i sfwrite i have to sox -x the files or so.
I've been running pd on LinuxPPC 1999 and 2000 without a hitch, using the "frags" option when starting pd.
If you're using LinuxPPC 1999, there may be some sound updates you need to download for enlightenment and gnome. Check the list archives at http://lists.linuxppc.org or ftp.linuxppc.org for info on the exact files.
If pd (or some other application) recognizes the sound drivers OK but you just get static, then it's an endian issue. There's a line of code in a file which I believe is called s_linux.c (I'm booted into MacOS right now so I can't check the exact name) which sets the format to SB16_LE. If you change that to SB16_BE then that should fix your endianess problems.
I've never had any luck with LinuxPPC getting MIDI or sound input to work on the Mac. So, to get around the problem, I bought a cheap ($30) Ensoniq AudioPCI Soundblaster card and installed the latest ALSA drivers. Under that setup, MIDI and full-duplex audio work great, though the sound quality leaves a little bit to be desired. I imagine higher end audio cards (and maybe even a few that support MacOS as well) might be supported by ALSA under LinuxPPC, but I haven't checked any out.
Good luck, and let me know if you have any more questions.

First, thanks for the tip on -frags/fregsize. All works fine. Of course there's no audio input and no MIDI.
However, 44.1 kHz rate dosn't work very well. I get a lot of clicking and distortion (even on the test-tone patch). Running in 22.05 kHz works better. Nevertheless i get clicks everytime I move mouse around. That seems to be coming only from the sound card. I tried the soundfile utilities things and while doing transforamtion it clicks like hell but the buffer plays back fine after....
Also, externs compiled fine! woohoo! except for loop~... And I see a lot has changed since the last time I used pd (v. 022 or something like that).
Any suggestions for a decent quality audio card compatible with ALSA? and hopefully supported by MacOS?
