I'm running CentOS 5 (Red Hat Enterprise 5) on a PC with audio
built into the motherboard. I also have Creative Labs PCI soundcards
CT4750 and CT4810 lying around.
When I go to the soundcard detection pane, the Intel card appears.
It shows
Model: 82801EB/ER (ICH5/ICH5R) AC'97 Audio Controller
Module: snd-intel8x0
The system plays sound. However, it doesn't record. I've tried two
different mics and various applications. I see no evidence that
the computer is receiving any input from the mic.
I also tried installing the Creative Labs cards, both with and without
disabling the Intel audio in the bios setup. No luck. I always get
sound playback, but no recording.
I'd really appreciate some help here. I REALLY need to get some audio
conferencing done on this machine. I'm in a REAL bind. Setting up a
new PC, even a Windows or Mac machine, is going to take time. I'd
rather use this machine if I can. But I am super, super busy and
I've already spent hours on this problem.
I've never had the slightest problem getting audio working on any
Windows or Mac machine. I'm trying to give Linux a go here, but there
is NO WAY I can afford to spend much more time on this kind of thing.
I've heard of people taking hours and hours and days and days to get
simple things done in Linux. I've also heard Linux advocates claim
those stories aren't true. My experience could go either way here.
So, here's your challenge. Help me get this working and I'll be a happy
camper. Prove to me I'm a fool for having this hard a time of it. I'd
love to admit I'm a total fool, if I can get this system working
without much more time. But if I do have to waste much more time on
it, Linux is out of here. I don't jump off a bridge with anyone or
anything. I won't use Linux or risk having other people here waste this
kind of time. |

From http://lists.debian.org/debian-kernel/2007/08/msg00685.html
try setting the number of channels to 2.

Check if the microphone channel isn't muted. Either use a graphical
mixer for that (KMix in KDE, don't know what in Gnome) or open a
Terminal, enter "alsamixer". After pressing tab you get to the input
section, make sure the microphone channel is neither muted nor at zero
volume.
If that doesn't help, check out the ALSA wiki:

To record from the microphone you must select the microphone as a
capture device.
Go into alsamixer, press F4, select the "Mic" channel, or whatever
it's called for your card (space bar toggles the channel once
highlighted).
If you're trying to record from the microphone, I wouldn't advise
unmuting the channel as another poster suggested; this would only
succeed in creating a feedback loop. Muting or unmuting is orthogonal
to recording. |
