From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20030206 Description of problem: Sound configuration properly detects the integrated sound chip on the Intel D845PEBT2 motherboard but no sound is played on normal front channel connection as in Windows. If speakers are connected to rear channel outputs, sound plays normally. It seems that 810_audio.o module is not handling 6 channel sound chip properly. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.Run redhat-config-soundcard 2. 3. Actual Results: Chipset is properly detected as intel 810 no sound plays is speakers are connected to normal lime speaker connector. Sound is played on rear channel (right and left) connector. Expected Results: Sound should come from lime connector Additional info:
I also have the Intel D845PEBT2 desktop motherboard, running RH 8.0.94, and can vouch that the sound does indeed come out of the rear speaker connector. But it comes out of the front speaker connector with Win/XP. This particular computer is dual-boot (my kids use it mostly), so its a pin to keep switching the speaker output.
It sounds like the driver is getting loaded properly. Once loaded, the driver is sending sound to the wrong output. This sounds like it is a driver problem rather than a redhat-config-soundcard problem. Transferring.
Seems Windows knows about the odd setup of this boardf and has drivers using non standard channels. We don't currently support doing that but it seems we need to look at it eventually

I haven't tried this yet (maybe this weekend), but I see that Intel now has Alsa sound drivers for their desktop boards here... http://developer.intel.com/design/motherbd/linux/ From the release notes... Devices Needing Additional Drivers to Function with Red Hat 9.0: · ADI* 1985 AC 97 audio will not function properly after a normal installation of Red Hat 9.0. Red Hat 9.0 will attempt to install and load AC 97 audio drivers and it will appear that the audio solution is properly configured when it really is not. Download the appropriate driver for the desktop board being used and install them using the instructions provided with the driver.
Thanks for the bug report. However, Red Hat no longer maintains this version of the product. Please upgrade to the latest version and open a new bug if the problem persists. The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, and if you believe this bug is interesting to them, please report the problem in the bug tracker at: http://bugzilla.fedora.us/
