when I start audacity, it complains that it cannot
open the alsa device (because the running jackd is using it)
debian:/home/demo/audacity-1.2.1cvs20040702#
/usr/local/bin/audacity ALSA lib pcm_hw.c:1155:(snd_pcm_hw_open)
open /dev/snd/pcmC0D0c failed: Device or resource busy
ALSA lib pcm_hw.c:1155:(snd_pcm_hw_open) open /dev/snd/pcmC0D0p
failed: Device or resource busy
I got that the first time - after selecting JACK in the I/O
preferences and restarting Audacity it was OK.
In the preferences, jack is selected, but when I try
to play a
sound, an error dialog pops up:
"Error while opening sound device. Please check the output device
settings and the project sample rate."
Maybe try stopping JACK, starting it and then starting Audacity again.
The project sample rate is set to 48000, which jackd
is running
at...
I've been using 44100 for all my tests - maybe that's the problem. I
also built portaudio v19 before building Audacity; that may make a
difference. From the audacity source directory created in the cvs
checkout, it's just:
cd lib-src/portaudio-v19
./configure
make
make install
then build Audacity as described.
Please report your experience on the audacity-devel list and hopefully
it can be sorted out.
