Hello all,
I'm running Denemo 0.8.4 on Ubuntu Hardy (gnome), with pulseaudio, without jack or lash. I'm new to Denemo and so far I'm really thrilled with it, so a big thanks to everyone who's worked on it!
The one problem I'm having is with playing notes as they're entered. The notes play fine, but after that Denemo will not play the normal midi output, and other sound on my system will not work until I close Denemo.
I get this message in my syslog:
pulseaudio[5935]: module-alsa-sink.c: Error opening PCM device front:0: Device or resource busy
And while the problem is occurring, lsof shows:
denemo 13256 blahblah 6r CHR 14,3 11891 /dev/dsp
The sequencer device in Denemo is the default /dev/sequencer, which I do have on my machine.
I've tried running as an ordinary user and as root with no difference. I also tried launching Denemo with pasuspender, but that didn't help either.
I'm getting this behavior with two laptops, so it's not specific to the hardware. However, they're configured quite similarly as far as the software goes.
Can someone help me out with this? Is there just a setting somewhere I'm missing? I keep thinking this must have an obvious solution.
Let me know what additional information I should supply.
Thanks,
Victoria
