Lucid: Scale wrong for audio volume (for USB046d:0a04 speakers)

[A.G. Nienhuis]

Binary package hint: pulseaudio

The volume control on the panel only works between 90% and 100%.

 90% on the panel === 0% PCM in alsamixer
100% on the panel === 100% PCM in alsamixer

I have volume buttons on my USB-speakers that change the volume by 10%. They are useless now. I need to use the mouse to move the slider one or two pixels to get the desired control.

In Ubuntu 9.10 it did work as expected.

This is a known bug with a lot of USB hardware, and its to do with the hardware drivers. Please try adding the PPA ubuntu-audio-dev/ppa and installing linux-alsa-driver-modules-2.6.32-14-generic and reboot. Please let us know if this fixes your problem.

[A.G. Nienhuis (a-g-nienhuis)]

That solves the problem!

(It's quite hard to do that from the live-CD without rebooting but it
possible)

[Daniel T Chen (crimsun)]

It's too late to merge the necessary changes into linux, and they're rather invasive.

In the meantime, please see https://wiki.ubuntu.com/DebuggingSoundProblems/KarmicCaveats#Volume range anomalies

Hi A.G.,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 531063

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

This is still an issue on Lucid with the latest updates as of today. (Kernel 2.6.32-22).

Note also that it's more than just a volume scale issue; my Logitech USB head set is pretty much useless at the moment, the volume is virtually inaudible. I'm using an old non-USB head set with regular audio jacks for my conference calls at the moment.

[hantms (han-thomas)]

NB: I tried installing linux-alsa-driver-modules-2.6.32-22-generic however this causes my computer to freeze when I insert the USB plug of the headset.

[Daniel T Chen (crimsun)]

You may want to use 2.6.34-rc6 or the latest daily build of 2.6.34.

[Nathan Kidd (nathan-svn)]

046d::0a13 (Logitech Z-5 Speakers) also have volume problems (~60~70% in volume slider is 0-100% in actual volume) with Lucid stock 2.6.32-22-generic kernel.

The 'load-module module-udev-detect ignore_dB=1' tweak fixes it.

[Daniel T Chen (crimsun)]

To be clear, ignore_dB=1 is not a fix.

[Nathan Kidd (nathan-svn)]

Pardon, "The 'load-module module-udev-detect ignore_dB=1' *works around* it.".

Is there still need to test the actual fix? Is there a recommended least-pain way of testing 2.6.34-* ?

[Gerrit Trawoger (gtrawoger)]

That issue is still up. My Logitech Z-5's would go from silent to blasting in one step (one press of the volume button).

The above method of adding the PPA and installing the alsa package does fix this. Just make sure you install the new alsa package when you update kernels.

This issue still exists in the current Ubuntu version; when plugging in a USB head set the volume in alsamixer is at zero. Note that the volume can NOT be increased through any GUI panel, the only way to use the head set is to open a terminal, type alsamixer and then hit the F6 function key, select the head set and then increase the volume to maximum.

@hantms, can you please file a separate bug using the "ubuntu-bug audio" command? Thanks!

[A.G. Nienhuis (a-g-nienhuis)]

I still need the workaround modules from the PPA

[Brad Figg (brad-figg)]

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 531063

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.
