It did help, I can actually hear noise that resembles the Enemy Territory game music somewhat... I think we're getting closer. Here's some more information that might be helpful. When I run the game using the normal kernel /dev/dsp oss emulation, it works fine. I captured the contents of the /proc/asound/card0/pcm0p/sub0/*_params when running without aoss, here it is: access: MMAP_INTERLEAVED format: S16_LE subformat: STD channels: 2 rate: 22050 (22050/1) period_size: 1024 buffer_size: 16384 tick_time: 1000 OSS format: S16_LE OSS channels: 2 OSS rate: 22050 OSS period bytes: 4096 OSS periods: 16 tstamp_mode: NONE period_step: 1 sleep_min: 0 avail_min: 1 xfer_align: 1 start_threshold: 1 stop_threshold: 1073741824 silence_threshold: 0 silence_size: 0 boundary: 1073741824 I thought I'd try putting the period_size and buffer_size in my .asoundrc to see what happens. But when I do this, the game can't "open" /dev/dsp: ------- sound initialization ------- /dev/dsp: Invalid argument Could not open /dev/dsp ------------------------------------ It seems to me there's a variety of things that could make oss_dsp_open return EINVAL or -EINVAL. Any ideas what to check next? - D ------------------------------------------------------- The SF.Net email is sponsored by EclipseCon 2004 Premiere Conference on Open Tools Development and Integration See the breadth of Eclipse activity.
