Hi, I am trying to enable a software mixer on an MIPS based embedded target board using alsa-lib v1.0.23. When I try to play two audio files using these commands: #aplay -vDplug:dmix song1.wav & #aplay -vDplug:dmix song2.wav" mixing works fine. For some strange reason when I try the same thing using the "nenad_dmix" device I am getting the following error: ALSA lib pcm_dmix.c:1068:(snd_pcm_dmix_open) unable to open slave aplay: main:654: audio open error: Invalid argument The error occurs while trying to open device for the second time (song2.wav playback). At the same time, song1.wav plays fine. The content of my .asoundrc is given bellow: pcm.nenad_dmix { type plug slave.pcm "dmixer" } pcm.dmixer { type dmix ipc_key 1024 ipc_key_add_uid false ipc_perm 0666 slave { pcm "hw:0,0" period_time 0 period_size 3840 buffer_size 15360 rate 48000 } } Could some of you help me to resolve this issue?
