Hi All,

I am using ALSA 1.0.24 with the attached asound.conf. I am attempting to share (mix) the analog output between Asterisk and aplay. However, when Asterisk is running, my application throws an error when attempting to play a wave file via aplay. If I stop Asterisk, aplay plays the wave file just fine. If I remove the asound.conf file, Asterisk and aplay are both happy and share the analog output just find with the default ALSA dmix implementation. However, we need this asound.conf to work for us for other reasons. What is wrong with it. I have even tried replacing dmix with dshare and get the same bad behavior. We are running CentOS 6.0. As a caveat, I am attempting to use dmix with analog audio. If I use it with HDMI audio, it works flawlessly (same asound.conf with tweek to specify HDMI). Thanks in advance for your help.

[root@devkrakorar ~]# aplay /usr/share/sounds/alsa/Front_Center.wav pcm_name = default ALSA lib pcm_dmix.c:1068:(snd_pcm_dmix_open) unable to open slave aplay: main:662: audio open error: Invalid argument

Best Regards,
