Hi all,
I'm trying to use csound with realtime output, but I always get the message:
Csound Version 4.23f03 (Nov 18 2003)
0dBFS level = 32767.0
orch now loaded
audio buffered in 441 sample-frame blocks
unable to open soundcard for audio output
I'm using the following flags:
-odac -B441 -b441 temp.orc temp.sco
instead of -odac I've also tried -odac0 through -odac6 with the same
result.
All my sound cards work fine in all other applications.
Some info:
$ cat /proc/asound/cards
0 [M2x2 ]: USB-Audio - MidiSport 2x2
M-Audio MidiSport 2x2 at usb-00:1d.0-1, full speed
1 [Mona ]: Echoaudio Mona - Mona
Mona rev.2 (DSP56361) at 0x20800000 irq 11
3 [VirMIDI ]: VirMIDI - VirMIDI
Virtual MIDI Card 1
The only strange thing I've done is I've installed alsa-driver-1.0.7,
built from source, to be able to use the Mona soundcard.
Does anyone know what csound does differently from other programs when
accessing the sound system?
Thanks,
Andrés
