Problem with microphone - OpenSUSE 11.3

I’m having Dell T1500 with SB 1040, and no luck with microphone working (yes microphone is checked and its working).
Some data that i read are needed.

I think i tried everything, but my knowledge about Linux systems isn’t solid. So if anyone could help me to get my mic working, so for example i could record with arecord it would be great.

Thanks for any help.


BTW. I hope i write this post in proper place, if not i’m sorry.

Hello apiekarski,

Welcome here.

The place you posted this (Multimedia) is good enough :wink:

Are you aware of thh fact that 11.3 is not supported anymore? That means not only that you do not get any more security updates, but also that not very many people here have 11.3 running. Thus it may be difficult to reproduce your problem. Or for people to think “How was that working in 11.3?”

Current openSUSE versions are 11.4 and 12.1.

Yep, i’m aware.

The problem is on my enterprise pc, and i’m a little affraid to upgrade. Cause if somethink goes wrong, i don’t have time to reinstall my pc.
Back to the problem. From my point of view everything looks ok, beside my mic doesn’t work. I see mic channel in kmix. It’s checked to capture. I tried front and back socket.
I feel helpless.

If someone be so nice and help me with this, i would really appreciate it.


thats the wrong command. The command should read:

rpm -q libasound2

ie you are missing the ‘a’. I think ‘a’ stands for ‘alsa’ in this case.

so your record devices are hw:0,0 (the analog) and hw:0,1 (the digital). Which one are you trying to use?

Thanks for script output link. I note this in mixer:

**!!Amixer output**

!!-------Mixer controls for card 0 [Creative]
**Simple mixer control 'Line',0
**  Front Left: Capture 115 [100%] [6.00dB] **[off]**
  Front Right: Capture 115 [100%] [6.00dB] **[off]**

ok, line mixer is OFF, but capture is jacked up to 100%. Why ? Thats inconsistent. Are you trying to capture with line ? If so, why have muted ?

**Simple mixer control 'Mic',0**
  Capture channels: Front Left - Front Right
  Limits: Capture 0 - 127
  Front Left: Capture 127 [100%] [12.00dB] [off]
  Front Right: Capture 127 [100%] [12.00dB] [off]

same comment. The Mic is muted but capture is jacked up to 100%. Why ? That’s inconsistent. Are you trying to capture with Mic (I assume yes)? If so you need to unmute it.

**Simple mixer control 'IEC958',0**
  Capture channels: Front Left - Front Right
  Front Left: Capture 115 [100%] [6.00dB] [off]
  Front Right: Capture 115 [100%] [6.00dB] [off]

This appears to be a digital Mic control ? < unsure > Again, same comment. The IEC958 capture is muted but capture is jacked up to 100%. Why ? That’s inconsistent. Are you trying to capture with IEC958 ? My guess is no, but I don’t know.

**Simple mixer control 'Digital',0**
  Capture channels: Front Left - Front Right
  Limits: Capture 0 - 120
  Front Left: Capture 120 [100%] [30.00dB]
  Front Right: Capture 120 [100%] [30.00dB]

Ok, thats the digital mic … hw:0,1 . Does it not capture ? What test did you do to test it ?

How about something like:

arecord -vv -f S16_LE -c 2 -D hw:0,1 new.wav

to record to file new.wav. Stop the recording by pressing <ctrl><c>

Check out those mixer settings I noted and fix them.

Thanks for you help oldcpu :slight_smile:

Chanels in kmix where off cause in my state i tried everything. Normally i leave them on, 1 of them, 2 of them, all of them.

I think Digital is only for output not as digital input, but i can be wrong.

As for libasound2, probably my retype mistake.

user@arksuse:~> rpm -q libasound2

I tried arecord with magic parameters :wink: and i get :frowning:

Last sentences stand for “arecord: pcm_read:1692: read error: Input/output error”

So i tried with hw:0,0 and got no error, but no sound with aplay too :frowning:

I’m lost, and helpless.

I can’t see your mixer settings, so I can not tell if you set them correctly after my caution in the previous post.

I do note this:

!!PCI Soundcards installed in the system !!--------------------------------------  03:00.0 PCI bridge: Creative Labs [SB X-Fi Xtreme Audio] CA0110-IBG PCI to PCIe Bridge 04:00.0 Audio device: Creative Labs [SB X-Fi Xtreme Audio] CA0110-IBG

where Creative Labs SB X-Fi Xtreme support has always been pathetic for GNU/Linux. I recall that some source code was passed to the GNU/Linux community, but even then to get it working was a bit of a hack. Whether that is related to your reported problem I can not say. Whether more recent GNU/Linux versions have addressed in a superior manner the poor X-Fi support that existed previous, I also can not say.
