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 at binky:~$ cat `which pd-ua25.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
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)".
