Re: [GnomeMeeting-list] Sound problem

[Damien Sandras <dsandras seconix com>]

Hi,

Probably the ALSA driver has a bug that doesn't show with the OSS
emulation layer used by Skype.

You can test if you get good results (or not) with this command:
arecord -D plughw:0,0 -c 1 -r 8000 -f S16_LE - | aplay -D plughw:0,0 -c
1 -r 8000 -f S16_LE - 

You can also test with -r 16000 instead of -r 8000.

Finally, notice that perhaps your USB HeadSet is plughw:1,0, not 0,0
