OSS *sometimes* has no sound

Statix · 2009-04-13 19:03:55

OSS is being really weird for me. When I first boot my system the sound never works. I'll go play with ossxmix a bit but ultimately change nothing, and sometimes it will randomly work, sometimes not. Sometimes I'll run an osstest and it will work and then the next one after does not work at all. Ultimately, really random and weird behavior.

For example, before I started typing this post it wasn't working. Now it's working fine. Ahhhh!

If it helps at all, alsa does not have any problems on this system. I'd love to be able to finally get OSS working though.

Do you have oss in your DAEMONS array?

Statix · 2009-04-13 19:37:04

Yes. Restarting it also doesn't seem to help at all. Only after it's been running for a while does it work.

Inxsible · 2009-04-13 19:43:58

I should have asked earlier, but you have blacklisted the soundcore module (which loads Alsa) correct? Or they would race to get the sound card.

Also,I noticed that your devices are HD Audio and USB. The wiki says that support for usb and hd is experimental (read buggy).

EDIT: But then again, this website says that Intel HD Audio and Intel AC'97 are both supported. Go figure !

I thought the OSS install script already got rid of the alsa modules so I didn't have it blacklisted. I blacklisted it though and the situation is still the same.

# lsmod | grep snd

Returns nothing.

I'm not actually using any USB sound devices atm. I think that's just there to say it has the potential for them. I used to have a usb mic plugged in and while I couldn't get it to work, it was detected and stuff and the situation was still the same with my primary card.

Just to share my experience: I had installed OSS while logged as user and X running and I could not get sound, only static. Reinstalled a few times with same results. Frustrated, I went back to alsa. Reading the wiki, I saw that I needed to exit before I install. So I did just that. Blacklisted soundcore module and alsa daemon in rc.conf, rebooted into init 3, installed OSS and everything worked.
