Hi list,
I just got a Roland/Edirol UA-25 to play with but can't get it working with pd under linux (Debian Etch). Playback via XMMS works, so I guess the problem is to specify correct buffer sizes. Anyone got a good command line to start pd with UA-25?
Thanks, Matthias

I have this card too.
If your pd has been compiled with --enable-alsa you should be able to choose it from the menu Media->ALSA. Then do Startup->Save all settings.
Ciao,

I can choose it from that menu but I get "snd_pcm_hw_params_set_format: Invalid argument" and "tried but couldn't sync A/D/A audio I/O stuck... closing audio" messages. I get the same errors on 2 different computers which run pd fine otherwise.
I forgot to say that I use pd 0.39-1test1 and ALSA 1.0.13. The sampling rate switch on the UA-25 is at 44100 and so is the setting in pd's media-alsa menu.
Thanks, Matthias

Preferably you should use 48000 with USB soundcards (or any other samplerate that is a multiple of 1000.)
Did you try the plughw:X devices in Pd's ALSA menu? And what about using OSS or jack?
Ciao

In fact I've noticed that I can achieve much lower latency (64x2 samples) since when I switched to 48000 with my UA-25.
But I didn't know that this setting was preferable.

Hi list,
I finally solved the problem: Upgrading to the newest versions of jack and pd in Debian Etch miraculously enabled me to start pd with jack. Pd with alsa alone still doesn't work - any explanations?
Thanks, Matthias

When I check the UA-25(plugin) device, pd crashes with this message:
*** glibc detected *** realloc(): invalid next size: 0x100fcc38 *** Pd: signal 6 pd_gui: pd process exited
OSS doesn't work either, here the error message is error: OSS: SNDCTL_DSP_CHANNELS failed /dev/dsp
Jack reports something interesting: Sorry. The audio interface "hw:0" doesn't support any of the hardware sample formats that JACK's alsa-driver can use.
Any ideas?
Thanks, Matthias

IIRC, I had the same error when I moved the sampling rate switch without rebooting. But I'm not sure.
Anyway, check the permissions on the /dev/ files too.
