[EN] (solved)No sound 3.9-0.towo.2-siduction-amd64

lspci | grep Audio
00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 06)
02:00.1 Audio device: NVIDIA Corporation High Definition Audio Controller (rev a1)

After rebooting from the dist-upgade, Phonon tells me it thinks that audio hardware has been removed and gives me the option to remove it, leave it or manage devices.

Testing all the devices for audio output, none of them work now.

Thanks

Can you still boot an older kernel? Maybe alsa has changed with newer kernel!


test with live cd, compare output of "lsmod | grep snd" between live cd and installation.

Assuming KDE desktop, my experience indicates you should "OK" to remove the audio hardware device, leaving only the pulseaudio server.  Use the "Test" button under systemsettings > multimedia to confirm that your pulseaudio server is working as expected. Also make sure you install pavucontrol -- you will need it.

Pulseaudio? This won't be default... will it? :shock:

Pulseaudio? This won't be default... will it? :shock:

I thought it already was default for KDE. Don't you have to deliberately remove it from a KDE default DE?

[towo]

Pulseaudio was never default in siduction and even kde does not need this shit.

[dibl]

........ even kde does not need this shit.

Well, OK, I am not one to make an argument online, especially with my favorite kernel engineer.



But, when I read this, which I admit is 12 months old, it seems to say that pulseaudio is needed to support phonon and kmix. That is why I think it must be a default element (not a mandatory element) of a standard KDE desktop.

I have seen pulse do a lot of damage, I, for one am not at fan at all

Pulse is a default of Gnome desktop though...

So when I boot my previous kernel:
3.8-7.towo-siduction-amd64

Phonon tells me I have seem to have removed devices and if I would like to remove them, like before, however this time it's reporting a different card as removed:
HDA Intel MID, 92HD81B1X5 Analog

and playback does work when I select my output device as:
HDA Intel MID, STAC92xx Analog

When I boot the newer kernel, the cards it thinks are installed are reversed. (i.e. It thinks the STAC92xx is removed and that the 92HD81B1X5 has been installed and none of the enabled devices will succeed in sound playback)

I don't know exactly how this problem could be solved. On lkml.org I read that the complete hda_intel stuff got reworked for 3.9 kernel. And the different behavior (different codecs for same hardware, but newone not working) between your 3.8.x and the new 3.9.x kernel seems to demonstrate that there are transition problems.
Only advice I can give so far:

- For the time being stay with the older 3.8.x kernel (if possible).
- Wait some days for new packages to come, maybe new alsa-utils solve this problem.
- File a bugreport to debian (using "reportbug", or maybe to the alsa-user mailing list)

But if *I* would *need to solve* this *now* with the new kernel I would *purge* all the alsa stuff (and if you have a ".asoundrc" in your home, better save it away)c, reboot and reinstall alsa. Without any guarantee.

EDIT://
How do you *know* the new codec / new device is not working? Did you check wheather or not the device is muted in kmix and/or alsamixer?

662   Sending a Bug Report
663   ~~~~~~~~~~~~~~~~~~~~
664   If any model or module options don't work for your device, it's time
665   to send a bug report to the developers.  Give the following in your
666   bug report:
667   
668   - Hardware vendor, product and model names
669   - Kernel version (and ALSA-driver version if you built externally)
670   - `alsa-info.sh` output; run with `--no-upload` option.  See the
671     section below about alsa-info
672   
673   If it's a regression, at best, send alsa-info outputs of both working
674   and non-working kernels.  This is really helpful because we can
675   compare the codec registers directly.
676   
677   Send a bug report either the followings:
678   
679   kernel-bugzilla::
680     https://bugzilla.kernel.org/
681   alsa-devel ML::
682     alsa-devel@alsa-project.org

Yea, I checked kmix and alsmixer, nothing is muted on the "new" device.

Alright, I'll file the bug and run 3.8 and check for fixed releases going forward.

Thanks Michaa7. Seems like I always show up with for help with crazy problems, but I always appreciate the help.

You might want to try aand rename phonondevicesrc (rename DO NOT delete)

Code: [Select]

/.kde/share/config/phonondevicesrc and then delete the hardware database

Code: [Select]

/var/tmp/kdecache-username/libphonon/hardwaredatabase and reboot, yes reboot

Just for shits and giggles, what does

Code: [Select]

apt-cache policy phonon-backend-null say
