Hello,
I am utilizing an external mic on my machine in conjunction with a
VF0560 Live! Cam Optia AF webcam. I am running CentOS 5.3 with the
kernel listed below and ALSA 1.0.20. I using the machine to stream
video with VLC 9.9 (see further below). VLC spits out the following on
the console of my machine whist capturing A/V and serving it up on the
network...ALSA 1.0.19 did not exhibit this problem while streaming it
did lock up after 20 minutes or so (audio could be heard on the VLC or
mplayer client with ALSA 1.0.19...just bits and pieces of audio every
now and then with ALSA 1.0.20. V4L is not the culprit here as video
streams and can be received without incident if I do not also capture
audio. The mic is plugged into the onboard sound on the motherboard. I
have not yet tried my USB mic with ALSA 1.0.20, but I will try it later
tonight. Any and all help would be greatly appreciate. Thanks in advance.
