Hello, my microphone does not work with my c-media CM8738 (builtin in asus a7v333 motherboard).
Using kernel 2.4.18

Adjusted mixer properties so that the recording input is the microphone. Volume is at max for microphone (play and record). No hardware mute on the microphone. I should be hearing the mike in the speakers without even recording, right?

Recording gives no error, but only silence is recorded. Used gnome-sound-recorder for the tests

Everything works fine on other OS with exact same hardware configuration.

The cmpci v.5.64 gave me this error, while trying to record I think, but it does not do so at every attempt.
cmpci: read: chip lockup? dmasz 65536 fragsz 256 count 0 hwptr 0 swptr 0

Tried latest: v.5.68; didn't give the error but I'm not sure it won't ever since I'm not able to reproduce it on v.5.64 (It just happens sometimes.)

Here's the startup output. Apart from the error, there are no other messages from the driver. 5.64 output is basically the same.

cm: version $Revision: 5.68 $ time 18:26:47 Dec 18 2002
PCI: Found IRQ 10 for device 00:05.0
PCI: Sharing IRQ 10 with 00:09.2
cm: found CM8738 adapter at io 0xb800 irq 10 chip version = 055
cm: Enable SPDIF loop

Audio output works perfectly.

Any help appreciated.
Thanks
Pierre
