improving the recording with the build-in mic

[Matthias Apitz]

Hello,

For voice calls I'm using the build-in mic of my laptop (in the upper
part of the lid). The recording is of poor quality. My environment is:

$ cat /dev/sndstat
FreeBSD Audio Driver (newpcm: 32bit 2007061600/i386)
Installed devices:
pcm0: <HDA IDT 92HD71B7 PCM #0 Analog> at cad 0 nid 1 on hdac0 kld snd_hda [MPSAFE] (1p:1v/1r:1v channels duplex default)
pcm1: <HDA IDT 92HD71B7 PCM #1 Analog> at cad 0 nid 1 on hdac0 kld snd_hda [MPSAFE] (1p:1v/1r:1v channels duplex)
pcm2: <HDA IDT 92HD71B7 PCM #2 Digital> at cad 0 nid 1 on hdac0 kld snd_hda [MPSAFE] (1p:1v/0r:0v channels)

$ mixer
Mixer vol      is currently set to  75:75
Mixer pcm      is currently set to 100:100
Mixer speaker  is currently set to 100:100
Mixer mix      is currently set to 100:100
Mixer rec      is currently set to 100:100
Recording source: mic

Is there anything I could do to higher the level of recording?
Thanks

	matthias
