It's my first bug report. I have an Acer Aspire 3003WLMi laptop with a SiS SI7012 sound card according to /proc/asound/oss/sndstat. This is the corresponding entry to the device in lspci: 00:02.7 Class 0401: 1039:7012 (rev a0) Subsystem: 1025:0083 Flags: bus master, medium devsel, latency 173, IRQ 18 I/O ports at 1400 [size=256] I/O ports at 1c80 [size=128] Capabilities: [48] Power Management version 2 This card uses the snd_intel8x0 ALSA driver and works pretty well, allowing hardware mixing AFAIK. Running two instances of aplay at the same time works and plays the two sounds simultaneously. However, hardware mixing doesn't seem to work with OSS emulation. With the snd_pcm_oss module loaded, running two instances of the "play" program doesn't work. The second one fails with the error: sox: Can't open output file '/dev/dsp': Device or resource busy I don't know if this is supposed to happen, is a bug or is my fault. If I use the "aoss" command to launch the "play" command, it works, like aplay. I recall having a card that allowed hardware mixing under ALSA, and being able to play several sounds at the same time under OSS too. That's why I find this strange. I don't have an ~/.asoundrc file. Thanks for your time and don't hesitate to ask for any missing piece of information relevant to the report, as I'm not sure what is exactly needed. Best regards and thanks again, -Ricardo García ====================================================================== ---------------------------------------------------------------------- pzad - 01-11-06 19:54 ---------------------------------------------------------------------- If you are using snd-intel8x0 driver, than your card doesn't have hw mixing. You are user of dmix. OSS emulation doesn't use dmix. You have to use alsa applications only or you can try to use aoss program with oss apps.
