Hi Guys,
On both computer 1 and computer 2, I plugged both a Cyber
Acoustics
CVL-1064 Desktop Microphone and a Logitech 980463-0403 into
the pink
"Mic" jack in the back (one at a time). If I click my
microphone'
On/Off switch, I hear a thump in my speakers. If I thump on
the mic,
I can hear the thumping in the speakers.
If I mute my microphone in gnome-volume-control, flicking my
microphone's switch only gives me a click and no thump.
Thumping
on the mic is not heard in the speakers either.
I tried recording from Audacity with no joy.
So I switched to "arecord".
$ arecord -L
default:CARD=ESB2
Intel ESB2, Intel ESB2
Default Audio Device
$arecord -d 10 -f cd -t wav -D default foobar.wav
which does record 10 seconds of me making noise into my
microphone into foobar.wav. Unfortunately, foobar.wav is
completely silent.
I can play other *.wav" file with "aplay" (and Audacity).
Is there any trick to recording from my microphone? Anyone
know what I am doing wrong.
Many thanks,
-T
New information! (I presume the same will reproduce on my
SL 6.1 machine).
The following actually *worked* on the my Fedora Core 15 live
CD 32 bit.
Pulse Audio was running:
arecord -d 5 -f cd -t wav -D front foobar.wav
Booting back into CentOS 5.7, both "-D front" and "-D default"
do not work (no joy).
Now this is funny. In CentOS 5.7, I have two "front" devices:
$ arecord -L
front:CARD=ESB2,DEV=0
Intel ESB2, Intel ESB2
Front speakers
front:CARD=NVidia
HDA NVidia
Front speakers
I think if I can figure out how to tell "arecord" I want the
"front" on the ESB2, not the nVidia HDMI, I can get this thing
to work!
Anyone have any ideas?
Many thanks,
-T
you're probably going to have to script alsa-config to set
your default to the onboard instead of the HDMI Sound or hook
a receiver to your HDMI line that has a line in/mic on it. http://www.seehuhn.de/pages/alsa you
might wish to look at this and dump a list of devices to see
what alsa's trying to set for it's default.
Hi Jason,
Thank you!
From the link you sent me:
- Why do I record only silence?
- Use alsamixer to make sure that you selected your microphon
[sic] input for
capturing data
- (use the
Capture view) and that the volume is up for
both the microphone line and the
- capture device.
Seems to be the problem, as my "Capture" device is set to "CD".
I had a bit of a problem figuring out how to change my capture
device to
"Mic" but then I found a reference to pressing the space bar to
switching
it over. Then still did not work and found I also had to turn up
"Capture's"
volume. And, still did not work and it was solved by turning up
the volume
from mute to normal on my speakers.
Thank you so much! This was driving me nuts!
