Hello!
* Patrick Shirkey <pshirkey(a)boosthardware.com> [2003-03-01 18:22]:
I have added some info to the asoundrc docs on using
the new dmix plugin
http://www.alsa-project.org/alsa-doc/doc-php/asoundrc.php3?company=Generic&…
It allows software mixing of multiple streams at one time in a similar
way to ESD,ARTS,JACK.
Great! This is just what I was waiting for. I guess it is thus
possible to use several oss and alsa audio apps plus jack at the
same time.
Currently it is only available with latest cvs so
needs testing with
various apps to make sure it works as desired.
I fetched and compiled it. The first instance of aplay works
fine. The second instance gives up with the following message:
player@adv:~$ aplay -Dplug:dmix stereo.wav
ALSA lib pcm_dmix.c:1434:(snd_pcm_dmix_initialize_poll_fd) unable
to open timer 'hw:CLASS=3,SCLASS=0,CARD=0,DEV=0,SUBDEV=0'
ALSA lib pcm_dmix.c:1583:(snd_pcm_dmix_open) unable to initialize
poll_fd
aplay: main:479: audio open error: Device or resource busy
What's going wrong?
Please note that I am only subscribed to the linux-audio-user-list.
