dapper: Regression with sound support between kernel 2.6.15-18 and -19

[Quim Gil]

I hope this is the right package to file the bug.

I installed Dapper Flight 5 and sound worked without trouble. Since then I'm upgrading available packages everyday. After yesterdays' upgrade (21/mar/06) the sound doesn't work anymore.

I've downloaded Flight 5 LiveCD and the sound works, so it definitely seems to be something related to the last upgrade.

hardware: Sigmatel STAC 9750 AC'97

Same here. I got an Creative SB Live 5.1

I've got my sound back after removing the KDE packages. Maybe arts is causing the error in sound...

[Quim Gil (qgil)]

Hi there. I have a Dell Inspiron 630m - can't find the sound card details, apparently a Sigmatel STAC 9750 AC'97 (?)

I haven't installed KDE, but I have of course the libartsc0 included in the ubuntu-desktoo metapackage. I won't remove it unless a Canonical developer tells me to do so (nothing personal Jieter, you know...) :)

Have you checked with alsamixer , that your master and pcm are not muted?

can you test with something like "mpg321" ?

[Quim Gil (qgil)]

I did check alsamixer/Volume control. Nothing mute, everything as it was 2 days ago when playing some music.

I have installed mpg321 and I've tried to listen some mp3. Although the "play" works, nothing is heard - same with Rythymbox, Totem, VLC, etc.

@ Quim Gil
I'm not sure arts is the cause of the problem.

@Sebastien Estienne
My computer hung when I tried to output audio to the sound card. It does not matter wether I used totem, beep-media-player, mplayer or mpg321

[Sebastien Estienne (sebest)]

have you tried booting on an older kernel revision from the grub menu?

[Jieter (jpwaag)]

@Sebastien Estienne
No, I did not, because it worked after removing all de KDE packages.

[Quim Gil (qgil)]

Sebastien no, I didn't think abolut this even when I though it could have something to do with kernel-image.

Well, the good news is that sound works with 2.6.15-18-386! It doesn't with the current 2.6.15-19-386.

[Sebastien Estienne (sebest)]

so you confirm that your regression with sound occured between
linux-image 2.6.15-18-386 and 2.6.15-19-386?

[Quim Gil (qgil)]

Yes, confirmed. Thanks for moving the bug to the right place.

[Ben Collins (ben-collins)]

Already fixed for next kernel upload.

[Quim Gil (qgil)]

Confirmed. It works with 2.6.15-20

Thank you!
