[Bug 441195] Re: [karmic][lucid] Intel HDA 82801G (ICH7) | STAC9200 - Mixer controlling wrong settings
@Daniel et al. This is not a driver bug. I investigated the driver and hardware a lot and discussed the issue in an ALSA bug report: https://bugtrack.alsa- project.org/alsa-bug/view.php?id=5031 As you can see in my last comment, I have requested that my bug report be closed, because I decided that ALSA is working correctly. The STAC 92xx chipset has two hardware volume controls, one for the L/R channel and one for the subwoofer (LFE) that is derived from L+R. But neither hardware volume affects the other. The so-called Master only affects the stereo internal speakers. It has no effect on the LFE volume. That's just how the chip is designed. :( The job of ALSA kernel drivers is to present an interface to what the hardware implements, so it is doing the right thing. AFAIK there is no social contract in ALSA that a hardware volume control named Master is multiplied with all others. If there were then it would be a design flaw, because there is nothing to stop chipset developers from making a product that is incompatible with that, as we are seeing here. It is not reasonable for the Linux kernel to attempt to provide functionality that does not exist in the hardware. To fix this issue, PulseAudio needs to either change the LFE volume in sync with the Master volume or use the PCM softvol exclusively, which is the work-around that I have adopted by adding load-module module-alsa- sink control=PCM to default.pa. The PCM approach is sub-optimal though because a software volume presumably incurs quantization error at low volume levels. See also the upstream bug at http://pulseaudio.org/ticket/457 I do agree though that it would be nearly impossible to work around this in PulseAudio and have it work for all hardware. I think the best solution would be for PA to have a blacklist of chipsets with dumb volume control designs and simply use the PCM control for them exclusively. ** Bug watch added: ALSA Bug Tracker #5031 https://bugtrack.alsa-project.org/alsa-bug/view.php?id=5031 -- [karmic][lucid] Intel HDA 82801G (ICH7) | STAC9200 - Mixer controlling wrong settings https://bugs.launchpad.net/bugs/441195 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Found a workaround for the Inspiron 9400 on Lucid based on Cristian's analog-output-lfe-on-mono.conf fix. 1. Edit the file analog-output-lfe-on-mono.conf (sudo gedit /usr/share/pulseaudio/alsa-mixer/paths/analog-output-lfe-on-mono.conf) Change: [Element Hardware Master] switch = mute volume = merge override-map.1 = all override-map.2 = all-left,all-right [Element Master] switch = mute volume = merge override-map.1 = all-no-lfe override-map.2 = all-left,all-right [Element Master Mono] required = any switch = mute volume = merge override-map.1 = lfe override-map.2 = lfe,lfe Into: [Element PCM] switch = mute volume = merge override-map.1 = all override-map.2 = all-left,all-right [Element LFE] switch = mute volume = merge override-map.1 = lfe override-map.2 = lfe,lfe [Element Master] switch = mute volume = merge override-map.1 = all override-map.2 = all-left,all-right Remove: [Element LFE] switch = off volume = off 2. Restart pulseaudio (pulseaudio -k). 3. Open sound preferences and choose from the output tab the Analog Output (LFE) connector. This fixed it for me.

[Bug 441195] Re: [karmic][lucid] Intel HDA 82801G (ICH7) | STAC9200 - Mixer controlling wrong settings
I am almost sure, I undid all the workarounds previously suggested in the comments (and Karmic Caveats), and with the attached pulse path the volume control is working fine. (both Master+LFE are equally affected first, then PCM) Alsa exports two analog volumes one for Master and one for LFE (this is usually called Master Mono) that controls the subwoofer. I think the confusion comes from the fact that if pulse controls the PCM (vía sink), it won't modify Master and LFE, but because it is an innermost volume in analog-output's path. Using the card this way fix to the max the two analog outputs and the volume range is shorter (only PCM). In addition, in my laptop if you set the volume of PCM to min, and the analog to max you still can hear noises. I think this is why there is a pulse path called analog-output-lfe-on-mono, by the comments on the file, it is supposed to correctly support this setup, but it wasn't being available because it expects a Master Mono element, that it is being called LFE by alsa's mixer. It would be nice Daniel T Chen could take a look to this. -- [karmic][lucid] Intel HDA 82801G (ICH7) | STAC9200 - Mixer controlling wrong settings https://bugs.launchpad.net/bugs/441195 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@Daniel T Chen: I am starting to think that this is a different issue than the one originally reported in the bug. In my case alsamixer seems to be controlling the right channels of my card, this is Master control the front speakers, LFE the subwoofer, PCM is the software volume.

[Bug 441195] Re: [karmic][lucid] Intel HDA 82801G (ICH7) | STAC9200 - Mixer controlling wrong settings
I think I found the problem and the solution. The Master and PCM are not interchanged they are right, the problem is that pulse's path for Analog Stereo assumes that the LFE is between PCM and Master, and this is not the case. For this kind of setups there is a path called Analog Stereo LFE on Mono. There is a comment at the beginning of the file that says ; Intended for usage in laptops that have a seperate LFE speaker ; connected to the Master mono connector But pulseaudio's debug information said this won't be enabled because the Element Master Mono wasn't available. I edited the file and renamed Master Mono to LFE and move it before Element Master and now it is working as a charm. Now pulse set PCM to max and the raises Master and LFE together. I attach my analog-output-lfe-on-mono. ** Attachment added: analog-output-lfe-on-mono.conf http://launchpadlibrarian.net/40929192/analog-output-lfe-on-mono.conf -- [karmic][lucid] Intel HDA 82801G (ICH7) | STAC9200 - Mixer controlling wrong settings https://bugs.launchpad.net/bugs/441195 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I found some related bug reports in PulseAudio and ALSA https://bugtrack.alsa-project.org/alsa-bug/view.php?id=4331 http://pulseaudio.org/ticket/457 To resume them briefly: The STAC9200's data-sheet says that the hardware has the following layout: front device - softvol plugin PCM -- hw device --- Master Volume |- LFE Volume LFE is a mono channel (L+R) connected to the subwoofer with it's own hardware volume. Pulse's developers assume that ALSA's master volumes should control all analog outputs (in this case LFE + Master). So the driver should be fixed. ALSA developers says that the driver's job is only to expose the hardware features, (in this case two separate volumes LFE, Master), and that higher level applications should take care of that. The reports are 14 months old...I don't think this would be fixed by either of them, maybe ubuntu should try to automatize the work around at pulseaudio install time? ** Bug watch added: ALSA Bug Tracker #4331 https://bugtrack.alsa-project.org/alsa-bug/view.php?id=4331 ** Bug watch added: PulseAudio sound server #457 http://pulseaudio.org/ticket/457 -- [karmic][lucid] Intel HDA 82801G (ICH7) | STAC9200 - Mixer controlling wrong settings https://bugs.launchpad.net/bugs/441195 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
