Linux mint 17 KDE one channel audio output [Solved]

Postby Lamb0 on Tue Jun 24, 2014 7:43 am

Hi all,

After installing the mint 17 KDE RC edition I noticed that I have only one channel sound output on my soundcard. This problem persists after applying all recent updates. The card is detected as "SB0570 SB audigy SE" and used to work fine under mint 14 KDE. Information about the card is as follows:

Code: Select all
*-multimedia
                   description: Multimedia audio controller
                   product: CA0106 Soundblaster
                   vendor: Creative Labs
                   physical id: 2
                   bus info: pci@0000:05:02.0
                   version: 00
                   width: 32 bits
                   clock: 33MHz
                   capabilities: bus_master cap_list
                   configuration: driver=snd_ca0106 latency=32 maxlatency=20 mingnt=2
                   resources: irq:18 ioport:d000(size=32)


When I use the onboard audio controller both channels work, also the soundcard works fine under Windows 7 x64. Both VLC and gstreamer backend have this problem. I would be glad to receive feedback on this problem.

Thanks in advance,

Lamb0

Hi Lamb0!
Maybe you'll find a hint in my help (see signature), chapter 5; especially I would search in the forum and the NET for your codec output.

Dear seeley,

Thanks you very much for your help. Running "alsamixer" and selecting my soundcard revealed that somehow the audio channel was turned off. Now everything works. It is however somewhat puzzling that it is not possible to change this parameter in Kmix, is it not?

Regards,

Hi Lamb0!
One day only with LM 17 KDE, I'm sorry that I don't have further ideas.
I've read somewhere (last year, I suppose it was on)
http://www.linuxquestions.org/questions/linux-forums-50/
that you can store the alsamixer setup with a special command, but I can't remember in which post.

Ok, I will have a look there. How do I mark the topic as solved?
