From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.1) Gecko/20031014 Description of problem: When installing Fedora Core 0.95 test3 on a Dell Dimension 4600c, the sound module is detected as i810_audio. Fedora thinks that its working fine, and doesn't report any errors. But I'm not getting any sound output (yes, it's not muted, etc). The hardware information itself is as follows: http://docs.us.dell.com/docs/systems/dim4600c/sm/specs.htm (click on the Home button on the page, it will follow through) Windows reports that the sound card is a "SoundMAX Integrated Digital Audio" and it works fine. The sound is provided by an on board chipset. This chipset has an SP/DIF output as well. Is it possible that its just directing the sound there instead of the regular audio ports? I couldn't find any utility in the distribution that would let me check this and change the setting if needed. I'm watching this bug report, so if any additional information is needed, just annotate and I'll try and provide it as fully as I can. Version-Release number of selected component (if applicable): kernel-2.4.22-1.2097.nptl How reproducible: Always Steps to Reproduce: 1. Fedora detects an i810_audio sound module during install. 2. It asks me if I can hear anything. 3. I can't hear anything. Actual Results: No sound. Expected Results: I should hear some test sound. Additional info:
It could be due to an IRQ routing problem. Have you tried adding the boot parameter "acpi=on"?
Just tried this, I get an error during the Interactive Startup phase when loading: /lib/modules/2.4.22-1.2097.nptl/kernel/drivers/acpi/toshiba_acpi.o: init module: No such device. No luck with that.
I can also reproduce this with kernel-2.4.22-1.2105.nptl
I can also reproduce this with kernel-2.4.22-1.2108.nptl
I have this on a Dell 400SC server too. Same symptoms. Same driver.
On a 4600c using the 2.4.22-1.2061.nptl kernel on a RHL 9 machine sound works fine. One thing I had to do was plug the connection into line out - not into the speaker jack.
As per Seth's comment, I was able to get it to work on line out using 2.4.22-1.2115.ntpl on Fedora Core 1. I'm updating the summary to reflect that it works on line out instead of speaker. It's using the i810_audio driver.
I just want to add that I appear to be getting proper two channel sound out of the line out jack. When I run redhat-config-soundcard, it says the following: Vendor: Intel Corp. Model: 82801EB AC'97 Audio Controller Module: i810_audio When I click on play test sound, the following happens on line out (in order): 1. Test sound from right speaker. 2. Test sound from left speaker. 3. Test sound from both speakers simeltaneously. If I try this with the speaker jack, I get nothing. Also, there was a typo in my kernel version. I'm using 2.4.22-1.2115.nptl, which is what was shipped with Fedore Core 1.
Fixed in Fedora Core 2. Sound now comes out of the correct speaker jack.
