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
The hardware information itself is as follows:
(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):
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.
It could be due to an IRQ routing problem. Have you tried adding the boot
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
When I click on play test sound, the following happens on line out (in
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.
