Karmic [9.10] issues with volume control, Master/PCM/LFE, and volume threshold

[dclaw]

Well... it's a little better.

Now, it gets to 70% and tops out instead of 25% in the volume manager app. The last 30% have no effect. The front output (which I'm not even using anyway) is at 100% now in alsamixer, but the PCM is now changed from 0->100 when I change volume in the app from 0->70%, then master goes from 74->100

Also, at 5% in the volume control applet, I don't get sound anymore, I get what I can only refer to as static.

Anyone have any other ideas?

dclaw:
Can you post the output of these terminal commands for me please:

uname -a
aplay -l
cat /proc/asound/version
head -n 1 /proc/asound/card*/codec#*

Terminal="Applications->Accessories->Terminal"
Please post text output using code tags. Also helpful is the make/model of your PC/Laptop.

Hi!
I too have a DELL Inspiron 9400/E1705 with the STAC9200. I've solved this problem by making some changes in the file "/usr/share/pulseaudio/alsa-mixer/paths/analog-output.conf.common". Try this:

sudo gedit /usr/share/pulseaudio/alsa-mixer/paths/analog-output.conf.common

You will find those lines near the bottom of the file:

[Element PCM]
switch = mute
volume = merge
override-map.1 = all
override-map.2 = all-left,all-right

So, add theses lines BEFORE:

[Element Master]
switch = mute
volume = ignore

and these lines AFTER:

[Element LFE]
switch = mute
volume = ignore

You should finally have:

[Element Master]
switch = mute
volume = ignore

[Element PCM]
switch = mute
volume = merge
override-map.1 = all
override-map.2 = all-left,all-right

[Element LFE]
switch = mute
volume = ignore

Save and quit. Then restart (restarting Pulseaudio isn't enough).

Using Fn + PageUp / PageDown or the media buttons now only modifies the "PCM" channel (have a look on alsamixer).

Works perfect in Lucid Lynx !!, i always had pcm 100% and noise, now i can control individualy pcm center lfe etc.. with alsamixer, Thanks!

Something similar worked for me on Lucid.

I used

[Element Master Front]
switch = mute
volume = ignore

[Element PCM]
switch = mute
volume = merge
override-map.1 = all
override-map.2 = all-left,all-right

on an ASUS M4A785TD-V EVO

It has the AMD 785G+SB710 chipset.

Anyway, the above works fine for me using the analog outputs with the hardware set to Analog Surround 4.0 Output, which is how I'm using it.

It works in Thinkpad T41 .

Thanks! This worked like a charm.

Worked for me too in Lucid with a Dell Inspiron 9400. Thanks.

Hello, I have a desktop computer with Asrock P4i65G with Multimedia audio controller : Intel Corporation 82801EB/ER (ICH5/ICH5R) AC'97 Audio Controller (rev 02).

I had the same problem on Ubuntu 9.10, 10.4 and 10.10 solved with your workaround. Thank you very much.

Does an official issue exist?

Could you explain how work the workaround?

Thank you so much. Fixed my sound on Dell Precision M90.

I am finally selling this laptop and building a new PC.. This issue plagued me for well over a year, every upgrade, every reinstall... I have applied this fixed many dozens of times, each time more annoying than the last...

To those of you left with this problem, open an actual ticket on launchpad or something, this thread has been here forever and hasn't drawn any attention to the issue and its not going to get fixed unless someone does something about it.
