today I installed openSUSE 11.4 (32bit) on my machine. So far, nice work. But I have some problems with KMix. When I open it, there are is only one Playback and one Capture device.
When I open “alsamixer” and click F5 to show all bars, it shows only two: “Master” and “Capture”.
But I need something more. Something like the Microphone boost. Without it, trying to use the microphone is useless…
Did you try a recording with the single capture channel (master volume/level) at max level in KMix? What application are you using to make the recording? When you activate it, you should get an application (volume) channel appear on KMix’s Capture Streams tab where you can adjust the level.

-close running copies of KMix
-left click on the KMix icon
-left click on the button “Mixer”
-mine has a menu: File, Settings, Help
-click Settings then click Configure Channels…
-available channels on the left, visible channels on the right
–move those on the left which you want to see, to the right
–move those you don’t want to see to the left
other settings are available via Settings > Configure KMix
after the report please return here and put the bug report number/URL

There are comments elsewhere on the forum about the initially empty Configure KMix panels so that appears to be normal, as it is on mine. Although I noticed for example, an entry appears in the right hand panel when an application’s capture channel appears on the Capture Streams (eg using Audacity). BTW that Capture Stream channel’s level for Audacity is at 50% on slider initially. I was able to increase it to get a good recorded volume level with my notebooks built-in mic, whereas on 11.3 I used Mic Boost.
However I can’t recommend Audacity for recording, as it doesn’t yet have native support for PulseAudio. It relies on the alsa plug-in for P/A, and I read that it isn’t very reliable according to Audacity. I eventually get latency problems and error messages. At least it proves the connectivity with P/A and recording level. Before testing I checked my mic using this at the command line (normal user):
arecord -d 10 myrecording.wav
For 10 seconds recording to wav file with any chosen name.
It seems that Mumble is not packaged by openSUSE and not in the standard repos or packman. I guess you sourced it from an OBS user’s home repo, so that makes it difficult to get support for it. I am not familiar with it. Does it have native support for PulseAudio?
BTW, you can install the package “pavucontrol”. It appears (to me at least) to offer similar features to KMix and Phonon (KMix>Settings>Audio Setup). There are slight differences when it comes to reporting status of streams.
So, I probably have to reconfigure PulseAudio. Any ideas how to do that? I’m not really familiar with PulseAudio and I haven’t found a GUI / Tool to do fine adjustments.
Yes, I already thought about that. But first I wanted to it “the SuSE way”.^^ Since I’m a Slackware user, I’m more familiar with ALSA. I wanted to test Mumble on another distribution, because Mumble caused some trouble on my Slackware.
I haven’t send a bug report yet. I’m not sure, if one can say that’s a bug for sure. I want to give it some more tries.
Glad you like it. As it’s a gtk app, I guess the KDE devs didn’t :D. For recording quality, best first check the FAQ and forum via the main Mumble web page for any issues.

No, I wouldn’t attempt that. You are already using the main user tool(s). If it comes to a bug report, the devs could advise on that as appropriate.
Did you try a test recording with “arecord” via the command line as I mentioned. If not, you should. It didn’t register on P/A, as it’s probably a much lower level operation using basic sound drivers. If that gives good quality, then it may point to a P/A bug, and Mumble may not provide adequate “evidence”. If arecord gives poor quality, then it’s either your hardware, or openSUSE doesn’t handle your sound device properly and that’s a bug report.

openSUSE Gnome used P/A by default all through 11.3, and now 11.4, and I believe ubuntu uses it as its default sound server.
Yes and no. I tried both.
Ok. On Mumble’s web pages, I came across this statement in a blog about the new recording feature of their latest release:
“Recording is only possible while you are connected to a server and you can only record what you hear or say.”
Since it looks almost like a native Qt app, I’m satisfied. But that doesn’t matter. As long it does it’s work, I’d also use an Application that uses Motif.
Once I had problems with PulseAudio. I had signal noise and delayed output due to a mis-configured PulseAudio. But it’s already about 2 years ago.
Not yet. I think I’ll try it tomorrow.
I disabled (not deinstalled) PulseAudio for testing ALSA. With ALSA no problems at all. OK, KMix still doesn’t show anything useful since it seems to use PulseAudio. (I think that, because there is only PulseAudio listed in the dialog KMix -> Configuration -> Audio setup)
If I come to the conclusion that it doesn’t work the way I want it to, I’ll go with ALSA.
Now with ALSA, my friends says I have a clear voice – and they say I’m really loud. ^^ I probably have to decrease the Mic Boost.
LOL! What happened?! My KMix is filled with channels! It’s title changed to “HDA Nvidia”. It like I selected “HDA Nvidia” in alsaconfig by clicking F6 and selecting it.
Í’ll test a few things… Maybe I can find out how I did it.
