Udoo HF-images recommended for better audioperformance!
=== Udoo version udoo_quad_ubuntu1204_v2.0.img [works] ===
pd-extended (ISSUES: broken audio pipe couldn’t sync A/D/A when doing fullduplex i/o with alsa and external usb CM106 soundcard – internal soundcard 2i2o working):
follow the guide in: http://www.udoo.org/forum/threads/guide-compile-pure-data-extended-on-udoo.478/
=== Udoo version udoobuntu-udoo-qdl-desktop_2.0rc2.img [works]===
(A1) compile pd vanilla (eg. 0.46-7) yourself:
download pd source for linux, extract tar.gz, go to pd-0.46-7 directory and compile pd with
./autogen.sh
./configure
make
sudo make install
— then run pd typing: pd
if problem (pd: error while loading shared libraries: libportaudio.so.2: cannot open shared) occurs, try:
(A2) compile pd external vor vanilla:
download source for pd externals
cd Download/external
make
=== Udoo version udoobuntu-udoo-qdl-desktop_2.0rc2.img [works]===
works with 2/6 i/o C-Media CM106 Like Sound Device (Conrad Electronics 7.1 Usb 2.0 Soundcard)
install pd:
sudo apt-get install puredata
make a patch with several i/o’s (io-testpatch.pd)
start pd from shell/ssh via wifi (ssh ubuntu@192.168.x.x) and try to lower audiobuf:
pd -nogui -audiodev 5 -inchannels 2 -outchannels 6 -blocksize 64 -audiobuf 15 io-testpatch.pd &
if pd crashes find process-id and kill it:
pgrep pd –> eg. 5665
sudo kill 5665
