This page provide general troubleshooting tips. If these cannot help to solve a problem with OSS, you may wish to consult the 4front support forum.
Contents
General
- Always read your driver's manpage. You can get the name of driver from 'ossinfo'.
 - Always test with osstest.
 - When consulting the forum, attach the output of 'ossinfo -v3' and 'ossmix'.
 
How do I...
- Change mixer settings - ossmix (command line), ossxmix (GUI)
 - Start and shut down OSS - soundon, soundoff (both require root)
 - Save and restore mixer settings - savemixer (saving requires write permissions for mixer.save)
 - Build OSS from source
 - Other Tips And Tricks
 
I can't hear any sound!
- Did OSS load at all?
 - Does osstest work?
 - Are the outputs muted in the mixer?
 - Is the default output (the one linked to /dev/dsp) the one connected / outputting sound in osstest? If not, see here how to change that.
 - HDAudio: Are the jacks detected by OSS as output, actually the jacks connected to the speaker?
 - Is this an hardware issue?
- Are the speakers muted?
 - Is the soundcard connected correctly to the speakers?
 - Do other drivers available for your OS (e.g. ALSA for Linux, FreeBSD native) work?
 
 
I hear noises!
- Many soundcards' hardware requires output mixers be set to less than maximum (60% at times).
 - Set vmix0-src to an higher setting.
 - Is the cable from the soundcard to the speakers connected correctly? Could it be too long?
 - Build and use OSS using the source from public hg repository.
 
I can't get multiple sound clients to play on the same device!
- multiple clients to same device aren't supported on FreeBSD version. Either set programs to use separate devices, or use sound server like aRts, esd, etc.
 - Is vmix loaded?
- If yes, Is vmix attached to the default output device? (Check if 'ossinfo -v3' shows more than one engine for the default output device).
 - (Doesn't apply to build 1016:) If vmix is not attached, make sure vmix1_masterdev in vmix.conf is set to the output device's device index (this can be determined via 'ossinfo -a').
