no sound on hp dv6500 pavilion laptop - pci id 8086:284b

[Nate Nuzum]

No sound at all
There are buttons on the laptop for muting and unmuting and volume control that respond on the screen:
mute button makes the mute graphic appear on the screen, and volume control adjusts the slider on the screen also
but there is never any sound at all

I can confirm the same bug here (hp pavilion dv6500) with a daily snapshot of gutsy (310807).

also, the light on the mute button is supposed to turn blue when the volume is unmuted, and although the mute icon on the screen appears and mutes or unmutes, the button light alwaystays orange

Maybe I found the upstream bug: https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3229

Same problem here - buttons appear responsive on the screen (volume marker moves, mute symbols appears on/off) but no sound....

[Mathieu Marquer (slasher-fun)]

Same problem. Something that may help for resolving the bug : there was no problem with the sound when using the Live CD (Ubuntu 7.04 i386) on this computer, but the sound disappeared at the first boot on the installed Ubuntu.

I tried the alsa 1.0.15rc2, and this version fix all the audio output for me (with many channels). But the microfone (and the line in) gets only noise.
For now, I'm using this kernel modules.

I don't know if this will get to gutsy.

With Ubuntu 7.04 the sound worked fine on my dv6543 after I re-compiled to the latest alsa driver. On Ubuntu 7.10 tribe 4 I managed to get the sound working with the attached patch, but with the 7.10 beta this patch did not work.

Same issue with Dell 1520 Gutsy Updated

00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 02)

any fix??

[Angelo Lisco (angystardust-gmail)]

This will probably be fixed after the release of gutsy as an update

You can monitor by yourself when an update of ALSA will be release by watching the ubuntu-gutsy backports module git tree:
http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-gutsy-lbm.git;a=summary
An initial upload of ALSA has just be done. Let's hope...
