I have been struggling for a week to seek out and find the answer to this problem on my own and am very frustrated.
I have a fresh, clean install of Ubuntu 10.04.1 LTS \n \l updated to kernal 2.6.32-25-generic.
After installing and updating and rebooting, I successfully replaced pulseaudio and alsamixer with oss4.2.
My sound card is a Sound Blaster X-Fi Extreme Audio pci (no e) ca0160
I ran osstest and had 5.1 working beautifully.
Then, I rebooted.
I ran osstest again and only sound came from front right, front left, center, and sub-woofer.
No sound came from surround left or surround right speakers.
I compared osstest results from before and after reboot and they match exactly.
I compared ossinfo -v3 results from before and after reboot and found this one and only mis-match between the two:
ossinfo -v3 before reboot shows: 1: oss_audigyls0 AudigyLS interrupts=744 (744)
ossinfo -v3 after reboot shows: 1: oss_audigyls0 AudigyLS interrupts=2215 (2215)
If this is the problem, how can I force the interrupts to where they should be and then make them stay the same on reboot?
I haven't tried yet but wonder if a work around is to run my oss4.2 installation script every time I start up
The other thing I see when I run ossinfo -v3 is this message:
tag: tip, date: Sat Sep 25 18:02:53 2010 +0300, summary: Fix a compatibility problem with Linux 2.6.36+.
Is this possible to do when the package manager shows 2.6.32.25.27 as the latest version?
Alternatively, should I try a different Linux all together such as Fedora?
