Hello everyone,

After much deliberation I finally bought a new laptop & installed Ubuntu on it. Then I got a DeMuDi kernel for audio work, and Jack for audio. I also installed Pd-0.38.4 - so far so good, everything worked right out of the box. Then I installed a number of other packages and upgraded to 39.2, this time compiling from source. Now, when I launch PD, I get the following:

couldn't open MIDI input device 0 couldn't open MIDI output device 0 opened 0 MIDI input device(s) and 0 MIDI output device(s). unknown audio API specified

Hi

Seems you have compiled pd without jack support. You need the libjack-dev library installed and watch out for the information that ./configure gives you.

You also have the option of backporting packages from Debian unstable: just add

deb-src ftp://ftp.de.debian.org/debian unstable main

to your /etc/apt/sources.list

then do (as root)

apt-get update apt-get build-dep apt-get source --compile puredata

This leaves you with a debian package puredata_xxx_i386.deb, which you can install with dpkg -i puredata_xxx_i86.deb

Guenter

unknown API unknown API unknown API .... unknown API audio I/O stuck... closing audio

sys_close_audio: unknown API 5

Evidently a jack/alsa problem here, but CD's for instance play fine in XMMS and alsamixer starts & runs fine, & qjackctl is active & rolling, so I'm not sure what the problem is... any ideas?

Thanks in advance,

David
