Logitech QuickCam Pro 4000 and SoundBlaster Live 1024 on Gentoo System

Post by the.th.. » Thu, 09 Jun 2005 06:38:04



I am trying to run my Logitech QuickCam Pro 4000 on my Gentoo system,
and the image part works perfectly, the problem is that appearantly the
soundcard in the camera is taking priority from my SoundBlaster Live
1024 soundcard which basically means that I only have access to my
input sound from my * and that I have no output.
This is pretty annoying as people would guess.
I have tried to search both the Usenet and Google Groups and have done
some general searches but I have not been able to find any answers to
my problem, I however found some old unanswered question on e.g. the
RedHat support site.

Any help would be appreciated.

What happens when you do (as root) 'modprobe snd-emu10k1'?  Are there
any error messages from the kernel?  What is the last few lines of
output from 'dmesg' immediately after the modprobe command?

Make sure that there is a snd-card-X alias for both cards, and that
both driver modules have the "index" option set in /etc/modprobe.conf:

alias snd-card-0 snd-emu10k1
alias snd-card-1 snd-usb-audio

options snd-emu10k1 index=0
options snd-usb-audio index=1

I have now set the aliases as you proposed and I have checked that the
module is probed correctly. However nothing happens and the *
still takes over the sound on the system.

Appearantly the emu10k1 module must detect the * as the soundcard
and then not detect the SBLive card.
This is also seen as I only have the snd-emu10k1 for the sound card and
that even though the pwc module for the * is not loaded the *
still takes over the soundsystem.

What are the contents of /proc/asound/cards and /proc/bus/usb/devices?

This is the old OSS driver.  Don't enable both OSS and ALSA drivers in
the kernel configuration, or put the line

audio

into the /etc/hotplug/blacklist file.

It didn't work to put audio into the hotplug list, as it doesn't use
hotplug. But looking in the kernel config I noticed that USB Audio was
enabled, I have now disabled this and appearantly it works :D YAY

Thank for all the help....

1. Logitech QuickCam 4000 Pro on Linux.

I'm running Mandrake 8.1 and trying to use a Logitech QuickCam 4000 Pro
(USB). The light on the camera is on but /dev/video has not appeared.

I just unplugged and replugged it and got the following in
/var/log/messages:

Jan 13 13:34:46 garcia kernel: usb.c: USB disconnect on device 3
Jan 13 13:34:55 garcia kernel: hub.c: USB new device connect on bus1/2,
assigned device number 4
Jan 13 13:34:55 garcia kernel: usb.c: USB device 4 (vend/prod 0x46d/0x8b2)
is not claimed by any active driver.
Jan 13 13:34:56 garcia /etc/hotplug/usb.agent: ... no modules for USB
product 46d/8b2/0

Here's a partial list of the output of /sbin/lsmod:

pwcx                   87072   0 (unused)
pwc                    38656   0 [pwcx]
videodev                4896   0 [pwc]
usb-storage            52236   0
usb-uhci               21668   0 (unused)
usbcore                59072   1 [pwc usb-storage usb-uhci]

The pwcx module was downloaded from:
http://www.ap-accessgrid.org/linux/usb.html
but I thought I could just modprobe pwc since it was already on my HDD.

Do I really need to recompile my kernel to use this camera?

Thanks,
Adam
