openSUSE 11.4 audio capture problem
 

Hi folks. There seems to be a problem with audio. Kmix will not start. The application "pocketsphinx" voice recognition is receiving interrupted input (confirmed by analyzing raw audio data) . I can record using Audacity. Alsamixer works but input levels are weak, must speak close to mic.

Ran ALSA diagnostics which appears to indicate some problems. The file can be perused here:

System:

OS: openSUSE 11.4 x86_64
Kernel: Linux 2.6.37.6-0.5-desktop
Desktop: KDE 4.6.00 rel 6
Machine: HP xw9400 AMD 64 Opteron
Chipset: nVidia nForce Pro 3600 and 3050 (proprietary Tyan Thunder)
Drive: OCZ Vertex 60 GB dedicated system--single boot
RAM: 4 GB ECC

Video: nVidia GT200 (GeForce 210) 512 MB
2D Driver: nouveau
3D Driver: swarst (no 3D acceleration) (7.10)

Audio: Onboard "card 0": nVidia MCP55 Analog Stereo
Onboard "card 1": nVidia Corproation Digital Stereo
Chip: Realtek ALC262
Alsa Driver: v. 1.0.23

Any help or pointers would be greatly appreciated.

Update: Just ran arecord for a test .wav. The playback is horrible and could hardly be understood.

Well, thanks anyway. I solved it myself. The openSUSE/KDE/Phonon/ALSA combo is not audio friendly. Installing the latest driver directly from the ALSA site and switching to a camcorder shotgun mic got it up and running.
