SDL and OSS

[SirDice]

I can't seem to figure this one out..

I've tried 2 games, freeciv and cube, both use SDL. Video works perfectly but I have no sound.

Soundcard is detected by oss:

Mplayer and a few other programs that use oss directly work as they should. SDL however doesn't..

I've tried setting a few of the SDL environment variables, pointing them to my dsp and mixer but this doesn't seem to help.

Any suggestions?

Freeciv output:

1: Error calling Mix_OpenAudio
1: Plugin sdl found but can't be initialized.
2: Proceeding with sound support disabled


cube:

init: sound
sound init failed (SDL_mixer): Couldn't set audio blocking mode

How old is sdl_mixer port?
Why are you using audio/oss instead of freebsd one?

error from cube points into oss not supporting asked feature.
Can you play multiple mplayers at once?

[SirDice]

How old is sdl_mixer port?
Up2date:

root@williscorto:~#portversion -vF|grep sdl
sdl-1.2.13_3,2 = up-to-date with port
sdl_image-1.2.7 = up-to-date with port
sdl_mixer-1.2.8_1 = up-to-date with port
sdl_sound-1.0.3 = up-to-date with port


Why are you using audio/oss instead of freebsd one?
AFAIK the fbsd sound drivers don't support my X-Fi.

Can you play multiple mplayers at once?
Yep, no problems there.

Oh.. If I set SDL_AUDIODRIVER to dma I get a slightly different message when running cube:

init: sound
sound init failed (SDL_mixer): DMA memory map failed


Freeciv message doesn't change, still complains about Mix_OpenAudio.

I'm out of ideas. Perhaps you may recompile sdl_sound and sdl_mixer and look what they detects(assumes) about your system.

Workaround: Try to use different SDL_AUDIODRIVER: esd, arts etc.

So am I :(

I already did.

Tried that (at least pcm and dma). I might resort to having esd as a backend. Haven't tried that yet as I was hoping I wouldn't need it anymore.

Report it on the OSS forums. You can also try upgrading your OSS from their mercurial development tree. There have been a few improvements for FreeBSD since the last released version.

FYI, cesium on #oss on Freenode (one of the OSS developers) mentioned to me that the development tree has a fix for libSDL-using programs under FreeBSD.

I've updated my system, OSS got updated to 4.1.b1052 in the process and I have sound again :)
