Open Sound System

by **Zodox** » Sat Nov 01, 2008 10:22 pm

Hello I just installed OSS on my FreeBSD box. I'm using digital sound output using a coaxial cable. The sound works, but the sound quality is really poor. I don't want any resampling or whataver just a bit-perfect pcm signal to my stereo.

Try setting vmix0-src to "Production" or "OFF" in the ossxmix mixer. Also try setting vmix0-channels to "Multich".
Lastly, you may wish to build OSS from the latest Mercurial source, since there are some FreeBSD improvements (e.g. you can disable vmix entirely by editing /usr/lib/oss/conf/osscore.conf).

Is it not possible to disable vmix in the OSS version from ports?

by **cesium** » Sun Nov 02, 2008 2:09 am

Yes. Older builds didn't support giving parameters to osscore so that vmix can be disabled... But setting vmix0-src to OFF is close as you can get on this OSS/FreeBSD version... Maybe you can test with "osstest" (or some other program that uses O_EXCL to bypass vmix) and see if vmix really affects sound quality. Anyway, upgrading may (or may not) bring other benefits...

P.S. test your cable too. It may be too long/otherwise unfine.

by **Zodox** » Sun Nov 02, 2008 10:24 am

Ok will do. The cable and everything is all good. I get alot better sound quality when I use Linux.

by **Zodox** » Tue Nov 04, 2008 1:33 pm

I have compiled OSS 4.1 (b rc2/200811041220) now. I disabled vmix in the configure script. The sound is better now, but I don't think I'm quite there yet . The highs can still sound a bit broken. I'm only playing CD quality flacs, using Music player daemon. Is it possible to see some details on what OSS does with the current playing audio signal?
