you may need to add this oxygen specific "mic source" and "front panel" into those conf files

Simple mixer control 'Front Panel',0

is this switch use to switch output between  front panel headphone and line out jacks ?

Before this patch, my card worked perfectly. I am now able to use it by choosing the 5.1 Profile with pavucontrol. With this fix however, I get maximum volume every time I restart the computer.. but this is probably another story.

Would this be the missing entry in aliases.conf?

it is ok if the above command list surroun40, surround51 , surround71

after doing so I have to recompile alsa, right?

The bootstrap script went well. The configure script finishes with "config.status:1610: error: cannot find input file: `Makefile.in'". I had to install several dev packages but that part worked I suppose. I added the log file for the config script if you want to have a look at it.

http://www.gnu.org/software/automake/manual/html_node/automake-Invocation.html


To create all the Makefile.ins for a package, run the automake program in the top level directory, with no arguments. automake will automatically find each appropriate Makefile.am (by scanning configure.ac; see configure) and generate the corresponding Makefile.in. 


this mean bootstrap.sh fail at the automake

Hello...

I'm another user of Xonar DX Card, reporting same bugs. Gnome Control Center Audio are troubled parsing all device port with this card because pulseaudio doesn't report any Analog Output Ports for this card.

From alsa-info.sh we can see this card has multichannel ports.

APLAY

  Subdevices: 1/1
  Subdevice #0: subdevice #0

Hovewer pulseaudio only report digital port output.

ports:
	analog-input-mic: Microphone
	analog-input-linein: Line In
	analog-input-aux: Analog Input
	iec958-stereo-input: Digital Input (S/PDIF)
	iec958-stereo-output: Digital Output (S/PDIF)

And profile combobox works correctly in gnome control center audio.

However, in about 10 seconds in gnome control center audio or when adjusting volume control manually, pulse audio coredumped.

complete patch to pa 5.0 fedora 21

Hello...

Just back from trip yesterday.

Hey thank you, now it's works properly. Volume control is working too.

Gnome control center audio can select audio analog out too since analog output port is properly reported by pulseaudio.

Attached complete patch that applied to my source.
All patch based on pulseaudio ver 5.0 fedora 21.

Just curious, is there a chance the patch go to next release of pulse audio?

you have to ask Tanu and Arun since 

e->merged_mask = 0xff;



may not be the correct fix as it change the logic 

seem it try to skip the virtual master playback volume

can you post the pulseaudio verbose log ?

http://cgit.freedesktop.org/pulseaudio/pulseaudio/plain/src/modules/alsa/mixer/paths/analog-output.conf


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

do pulseaudio need a 8 channel override map for those 8 channel master playback volume control ?

 > W: [pulseaudio] alsa-mixer.c: Volume element Master has 8 channels. That's too much! I can't handle that!

I think the short-term fix would be to just ignore Volume element Master. Long term we could think about supporting it correctly.

Meanwhile, just comment out the "[Element Master]" section in /usr/share/pulseaudio/alsa-mixer/paths/analog-output.conf should solve the problem for this card (but might cause problems for other cards).

Yeah, I don't think this part is correct either. It will probably regress other cards.

does it really fix since you still need to set all eight channel of those volume control to 0dB ?

1) some notebook with  hda codecs (e.g alc260) which have stereo Master plaback volume control instead of the virtual master playbav volume
2) most multi channels usb audio card have these kind of playback volume control

That's why I called it a "workaround patch", not a fix. :-)

If the user wants to change this 8-channel volume control, (s)he will have to use ALSA to do so (e g alsamixer or amixer).

should e->merged_mask be ininitalised in function element_probe ?

the current logic is also broken


      if (e->has_dB) {
                if (!p->has_volume) {
                    for (t = 0; t < PA_CHANNEL_POSITION_MAX; t++)
                        if (PA_CHANNEL_POSITION_MASK(t) & e->merged_mask) {
                            min_dB[t] = e->min_dB;
                            max_dB[t] = e->max_dB;
                            path_volume_channels |= PA_CHANNEL_POSITION_MASK(t);
+                          p->has_dB = true;
                        }

-               p->has_dB = true;
          }
