Hello All,
I am a newbee to LinuxAudio and am trying to get a headset microphone working.
Here is some results from testing that someone else did on another site for their system.
cat /proc/asound/pcm
00-04: Intel ICH - IEC958 : Intel 82801DB-ICH4 - IEC958 : playback 1
00-03: Intel ICH - ADC2 : Intel 82801DB-ICH4 - ADC2 : capture 1
00-02: Intel ICH - MIC2 ADC : Intel 82801DB-ICH4 - MIC2 ADC : capture 1
00-01: Intel ICH - MIC ADC : Intel 82801DB-ICH4 - MIC ADC : capture 1
00-00: Intel ICH : Intel 82801DB-ICH4 : playback 1 : capture 1
arecord --list-devices

arecord -f dat -D hw:0,1 -d 20 test.wav

Recording WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo
arecord: pcm_read:1473: read error: Input/output error
In each case above, the file test.wav is 44 bytes
but,
arecord -f dat -D hw:0,3 -d 20 test.wav
the file test.wav is 3840044 bytes but has no sound when I play it back.
I have no idea how to use alsamixer, so I do not know if there is a problem there or what.
I downloaded a script called alsa-info.sh and ran it. It gave extensive information about my system, but I could not understand most
of what it output and how to identify my problem from the information.

Could someone please point me in the right direction(s) to getting my microphone working? The sound works fine!
