moin Ede, moin list,
Well, I'm successfully running both MIDI and audio off the UA-25, also on debian (mostly) etch, and a ThinkPad T42...
First of all, don't use OSS (emulation) -- I've had no luck here with the UA-25 in "advance mode" and Pd; as you say, probably due to 24-bititude.
Do you have an ~/.asoundrc defined, and if so, what's in it? If you're choosing from the pd "Audio Settings" menu, grab the "UA-25 (plug-in)" entries, rather than one of the "hardware" entries. Also, I've had to run pd with the "-rt" switch (which required getting realtime capabilities patches working: urgh) when using ALSA directly, otherwise I get audio pops and eventual "tried but could not sync" errors. fyi, I run pd here with:
moocow@binky:~$ cat which pd-ua25.sh
#!/bin/sh
( pd -rt -r 48000 -alsa -channels 2 -audiodev 6 "$@" & )
( sleep 5 ; aconnect-usb2pd.perl; jack-chrt.sh )
... where "aconnect-usb2pd.perl" does some magic with 'aconnect', and the (badly named) 'jack-chrt.sh' messes around with some scheduling priorities.
Important to note:
- pd's sample rate should probably match whatever you've chosen on the ua-25
- use alsa.
- for me, "-audiodev 6" is the 6th entry in the drop-down list of audio
devices I get with the ua-25 plugged in (under normal circumstances), labelles "UA-25 (plugin)".
good luck, Bryan

After reading on the list about Edirol UA-25 I went out and got
one on run on Debian. I can get sound when running in standard mode
or midi in advanced but can't get both. I read on the list that some- one is running both midi and sound. Problem is the UA-25 seems to
force 24bit in advanced mode which Pd won't run at or is there a way
to get around this. Debian Etch Power Book 1.5 Edirol UA-25?
