alsa mixer channels missing after upgrade to linux-image-2.6.22-10-generic with Intel / Nvidia HDA chip

[JoergMechnich]

Binary package hint: linux-image-2.6.22-10-generic

After upgrading the gutsy kernel from linux-image-2.6.22-9-generic to linux-image-2.6.22-10-generic, there are only three playback controls left in the mixer. Recording controls are missing completely.
Playback with headphones is also far to quiet, so even with completely raised levels of the master and PCM mixer controls I get only very low output. This probably means that the automatic amplification for headphone output is not working.

Output from amixer:

Maybe the output of lsmod could also be of help.

[schalkpd (schalkpd+launchpad)]

I can confirm this. On the same sound hardware (in a macbook), I cannot hear any sound output from internal speakers or over a set of headphones (perhaps due to lower-power speaker/headphones) and am missing the same audio channels.

[steavieleeking (steavieleeking)]

The same on Thinkpad T60 with Intel 82801G. Also sometimes i don't even have PCM, just MASTER.

[Kyle S (pissboy)]

Confirming on my T60 with 82801G as well, including PCM going missing intermittently. It works fine on -9, broken on -10. Unfortunately I am reluctant to go back to -9 for normal use because of Very Annoying Bug #129226 which is fixed in -10 !

One other detail: the "PC speaker" system bell noise is at normal levels, but I can hear nothing else thru speakers or headphones.

[harrydb (harrydeboer)]

I have the same I guess, but on different hardware (also uses the snd_hda_intel driver though)
Using 2.6.22-9-generic it works straight away but with 2.6.22-10-generic mixers are gone and the alsa device name changed a little. Feisty also had this behavior by the way, I used snd_hda_intel supplied by Via to solve that.

From the mainboard specification: VIA VT1708A High Definition Audio
From lspci:
02:01.0 Audio device [0403]: VIA Technologies, Inc. VIA High Definition Audio Controller [1106:3288] (rev 10)
        Subsystem: VIA Technologies, Inc. Unknown device [1106:aa09]
        Flags: bus master, fast devsel, latency 0, IRQ 22
        Memory at dfefc000 (64-bit, non-prefetchable) [size=16K]
        Capabilities: <access denied>

[Markus Strobl (mstrobl2)]

Confirming on my HTPC using ALC883 chipset (snd_hda_intel driver). I lost many mixer channels. Most importantly the IEC958 (digital output switch) which means I no longer have sound at all. Had to revert back to 2.6.22-9 which made it work again.

[Alexey Balmashnov (a.balmashnov)]

Another confirmation. Dell Inspiron 640m with

00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01)
        Subsystem: Dell Unknown device 01d8
        Flags: bus master, fast devsel, latency 0, IRQ 20
        Memory at efebc000 (64-bit, non-prefetchable) [size=16K]

        Capabilities: [60] Message Signalled Interrupts: Mask- 64bit+ Queue=0/0 Enable-
        Capabilities: [70] Express Unknown type IRQ 0

By the way, this is also regression w.r.t. feisty, since in feisty it worked ok.

[Pascal Potvin (pascal-potvin)]

Added the alsa-driver package, to be sure everyone gets the info.

The bug is also true for Nvidia HDA chips, you can look in the duplicates for more info.

Major regression.

[Manuel Olbrich (dschie)]

same problem here.
00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)
at my t60. here are master and pcm left, but the master-slider has only 4 possible positions (0%, 25%, 50% and 100%)

[Markus Strobl (mstrobl2)]

Just checking if anyone else saw what I saw: 2 days ago I got a new kernel modules package. When I booted after installing this package it seemed the audio channels were back to normal but I couldn't start X as it said my nvidia kernel module failed to load. So it fixed audio but broke video?

[steavieleeking (steavieleeking)]

Audio is working here too; but ATI fglrx doesn't load any more.

[cake (tom-polybonk)]

My nvidia MCP51 HDA is working again for me with kernel modules update, my nvidia 7600 card works fine after update as well.

Asus A6T

[Markus Kienast (elias1884)]

Since again, I had to attach the same lspci file to several bugs again, I want to make all devs and bug fixers aware of this bug https://bugs.launchpad.net/malone/+bug/3382

I find it is absolutely necessary to be able to attach hardware profiles to launchpad user accounts. I would then simply say, this happens on Feisty on my machine XY and you guys could immediately access the right record in the HW DB. Now you have to over and over again request us to send lspci outputs, lshw outputs, ....

Isn't it the purpose of programming to relieve us from things that we have to do over and over again in exactly the same way? Isn't that what computers are for, to do exactly these stupid always the same operations?

Please use your voice as bug fixers, as the people most annoyed by this, to get canonical to implement such a feature in launchpad!

[JoergMechnich (joerg-mechnich)]

Audio is working again for me too after some kernel(-module)-related updates.

A side note for people having trouble with fglrx: after getting trouble with the fglrx module delivered with the linux-restricted package I compiled the newest 8.40.4 driver from source packages that one can generate with the ati installer (also for gutsy now). Since then everything is working fine again. Only thing to remember is that you _have_ to run sudo depmod -a manually after installation of the module.

[Markus Strobl (mstrobl2)]

My comment from 8/28:

Just checking if anyone else saw what I saw: 2 days ago I got a new kernel modules package. When I booted after installing this package it seemed the audio channels were back to normal but I couldn't start X as it said my nvidia kernel module failed to load. So it fixed audio but broke video?

----------------------------

Turned out that I had to do a "sudo depmod -a" after booting the new kernel. Once that was done the nvidia_new kernel module loaded and X could be started.

So fix is confirmed. Audio (and video) works again with the new release of the kernel-modules.

[steavieleeking (steavieleeking)]

"sudo depmod -a" also brings back fglrx driver.

[Markus Kienast (elias1884)]

Bug was resolved with last kernel update on my system.
