I'm running Ubuntu 9.10 with OSS4 compiled from mercurial source code repository and my sound card is SB Audigy SE. My problem is, that my rear left speaker doesn't produce sound - only the right one does (tested with osstest and in the system by playing music). The rear speakers work fine, as they play normally when I attach them as the front speakers.
Furthermore, in ossxmix the "rear" slider doesn't control the volume of rear speakers. It does nothing actually.
For a dirty workaround, I switched the rear speakers jack with center/lfe jack. In that case only the subwoofer plays so I came up with an idea to leave the center jack in a position, that both subwoofer and center speaker play in mono. Although it somehow works, OSS now thinks, that my rear speakers are the center ones, so eventually it's not really a good idea to leave it as it is.
Is there a more elegant way, to make it work?
Regards,
phan
