I have no sound input from my microphone. With a fresh install of 11.4/gnome desktop it was working.
Then all I did was installing the multimedia support from the script in the opensuse guide (which interestingly includes some files for k3b so I suspect there is a conflict of libraries now that some kde libs have been installed) and a full system update. After that, my mic has stopped working.
Ok I note an HP-Pavilion (product Name: AY687AA-ABM MS220la) running a 32-bit openSUSE-11.4 with the 2.6.37.6-0.5-desktop kernel, and alsa driver version 1.0.23 and the alsa Utilities version 1.0.24.2. The hardware audio codec is an ALC269.
I note from the arecord one hardware audio capture device:
ARECORD
**** List of CAPTURE Hardware Devices ****
**card 0**: SB [HDA ATI SB], device 0: ALC269 Analog [ALC269 Analog]
Subdevices: 0/1
Subdevice #0: **subdevice #0**
ie it is also known as: hw:0,0
I note from your mixer that the boost is at 0% making it difficult (impossible ? ) to capture audio:
**!!Amixer output**
!!-------------
**!!-------Mixer controls for card 0 [SB]**
Card hw:0 'SB'/'HDA ATI SB at 0xf8700000 irq 16'
Mixer name : 'Realtek ALC269'
**Simple mixer control 'Mic Boost',1**
Front Left: 0 **[0%]**
Front Right: 0 **[0%]**
**Simple mixer control 'Capture',0**
Front Left: Capture 31 [67%] [14.00dB] [on]
Front Right: Capture 31 [67%] [14.00dB] [on]
You should move your PCs boost up to 67% or so.
When testing a recording functionality, for testing purposes I always use the arecord command … for example:
arecord -vv -f cd test.wav
or
arecord -D hw:0,0 -vv -f cd test.wav
where I used the hw:0,0 in this example which I think corresponds to your PC’s “card : sub-device”
I also find in openSUSE-11.4 it is useful to install the application pulse audio volume control ‘pavucontrol’ and carefully setup its configuration, input device, and recording tabs so as to ensure audio capture takes place. Ensure in the “SHOW” filter at the bottom of the pauvcontrol tabs are set to show ‘all devices’ and ‘all steams’.
I was having the same problem and the way i fix it is open terminal type alsamixer then F6 ( select sound card) and boost the microphone and so on … hope this will help you
You have 2 hardware devices listed as capable of recording audio. Ensure you have the correct one selected.
I note you have openSUSE-11.3. Is this Gnome or KDE ? If KDE then my pavucontrol advice is not applicable.
I note you have snd-hda-intel: model=6stack applied. Why ? Did you find that the only option to use to get your audio to work ?
Note the alc880 has many options that can be applied instead of 6stack:
ALC880
======
3stack 3-jack in back and a headphone out
3stack-digout 3-jack in back, a HP out and a SPDIF out
5stack 5-jack in back, 2-jack in front

6stack 6-jack in back, 2-jack in front

medion Medion Rim 2150
test for testing/debugging purpose, almost all controls can be
adjusted. Appearing only when compiled with
$CONFIG_SND_DEBUG=y
auto auto-config reading BIOS (default)
Do any of those work any better ?
Note according to the ‘amixer’ content in the diagnostic script you have the mic muted making it not possible to record audio.
You NEED to fix your mixer settings as you appear to have them wrong.
I’m on vacation, travelling on the road, with very limited Internet access, and not able to provide you more detail. I’ll be back home in 10 days and able to help more then.
