[Bug 35717] Re: 'Master' needs to be exchanged with 'PCM' in order for volume hotkeys to work
I've just noticed I can now change the mixer the multimedia-keys use. (Feisty ;-) This makes this bug even lower priority. It would off course be great if this would be set to PCM by default when this type of soundcard is detected, but at least there is an easy workaround for the multimedia- keys now. -- 'Master' needs to be exchanged with 'PCM' in order for volume hotkeys to work https://launchpad.net/bugs/35717 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 35717] Re: 'Master' needs to be exchanged with 'PCM' in order for volume hotkeys to work
The bug currently says 'needs info' .. what type of info is needed? My soundcard does _not_ have a master. Only a PCM and Line-In volume. The perfect solution would be to have a virtual-master-mixer that changes both. But even a setup, where the master would just use the PCM would be a much better situation than the current one. Can this be fixed now? Its a simple -if this is the soundcard- then use this type of alsa-config .. -- 'Master' needs to be exchanged with 'PCM' in order for volume hotkeys to work https://launchpad.net/bugs/35717 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I'm using the most up to date Edgy and it is still valid. The bug-status says 'needs info'. What type of info do you need? The output of lspci.txt with edgy is added once again to this message. If you need me to test/try/do whatever, please tell me. In the mean time, does any one know a possible workaround. I need the volume+up/volume+down and mute keys to control the pcm channel instead of the master. The master channel seems to be totally ignored. So what would work for me is something that makes the gnome-desktop perform the correct action, or something that sort of virtualizes the master volume. ** Attachment added: sudo lspci -nv lspci.txt http://librarian.launchpad.net/4740101/lspci.txt -- 'Master' needs to be exchanged with 'PCM' in order for volume hotkeys to work https://launchpad.net/bugs/35717 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 35717] Re: 'Master' needs to be exchanged with 'PCM' in order for volume hotkeys to work
According to this thread I found, the alsa developpers do not consider it a bug: Found at: http://lkml.org/lkml/2006/8/10/84 I've cut and paste the relevant part here: (quote) [1.] One line summary of the problem: While using snd_via82xx the PCM volume is not responding to changing Master Volume. [2.] Full description of the problem/report: The issue is quite simple, but I am suspecting the driver to be the cause (?). The sound for my chip works perfectly fine, but somehow the PCM volume works only for DSP. The Master Volume works only for the remaining sources (Line in, CD in). It's no bug. The ac97 codec chip on your board has really no volume control. The PCM volume is an alternative volume control using DXS control in the via823x control chip. Takashi (end quote) In other words, Master controls Line-In CD, whereas PCM controls the audio-output. Which is the same behavior I've experienced. It's just the way the hardware works. So I suppose this bug should actually be assigned to another package! Which package is responsible for assigning volume-up/down to the multimedia keys? -- 'Master' needs to be exchanged with 'PCM' in order for volume hotkeys to work https://launchpad.net/bugs/35717 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 35717] Re: 'Master' needs to be exchanged with 'PCM' in order for volume hotkeys to work
The .asoundrc file which i cut paste below this comment seems to do
the trick for me. I can't confirm wether or not Master now also controls
the cd and line-in volume, but at least it controls the PCM.
Its from: http://alsa.opensrc.org/index.php?page=cmipci
I've changed control { name SoftMaster to Master } from what they specify.
It's a big hack and I have little to no clue why it works or what it
doet, but it does the trick :-) Yeah!
One note: muting the master volume control does not mute the pcm
unfortunately. So if anyone understands what this .asoundrc file format
is about and knows how to tweak this, i would like to hear it!
pcm.softvol {
type softvol
slave {
pcm hw:0,1
}
control {
name Master
}
}
pcm.dsp0 {
type plug
slave.pcm softvol
slave.channels 6
route_policy duplicate
}
pcm.!default {

Is this symptom still valid in 6.06.1? If so, please attach the output from ``lspci -nv''. ** Changed in: alsa-driver (Ubuntu) Sourcepackagename: alsa-driver = linux-source-2.6.15 Status: Unconfirmed = Needs Info -- 'Master' needs to be exchanged with 'PCM' in order for volume hotkeys to work https://launchpad.net/bugs/35717 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 35717] Re: 'Master' needs to be exchanged with 'PCM' in order for volume hotkeys to work
This sympton is still valid. The master volume is totally ignored (including wether it is muted or not). I have to change the PCM slider. Which means that the default settings in Ubuntu do not work for my setup. Volume applet still needs to point to the PCM and I had to connect the volume-keys on my keyboard using the gconf-editor. I've done a sudo lspci -nv lspci.txt and attached the generated lspci.txt file. I hope it helps. I can manage, but if you need any more information or specific tests, please let me now. If this gets fixed before Edgy it might prevent some bad review and some dissapointed new linux users :-) -- 'Master' needs to be exchanged with 'PCM' in order for volume hotkeys to work https://launchpad.net/bugs/35717 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
