sound stopped working after attempting to install webcam module


Hi Guys,

I've found a lot of people with similar problems on this forum but somehow the solution to my sound agrivations still linger.

I think trying to install the quickcam module that I downloaded and compiled has somehow ousted my sound driver. It might be a securities issue, but I don't know what that means.

Any help will be greatly appreciated.

Code:
>> aplay -l
**** List of PLAYBACK Hardware Devices ****
so aplay doesn't see any hardware devices, but

Code:
>> lsmod | grep snd
snd_mpu401             12777  0 
snd_mpu401_uart        12225  1 snd_mpu401
snd_intel8x0           36061  0 
snd_ac97_codec         96613  1 snd_intel8x0
ac97_bus                6465  1 snd_ac97_codec
snd_seq_dummy           7877  0 
snd_usb_audio          79553  2 
snd_seq                50609  1 snd_seq_dummy
snd_usb_lib            19777  1 snd_usb_audio
snd_rawmidi            26817  2 snd_mpu401_uart,snd_usb_lib
snd_pcm_oss            43457  0 
snd_mixer_oss          19521  1 snd_pcm_oss
snd_seq_device         11981  3 snd_seq_dummy,snd_seq,snd_rawmidi
snd_pcm                74949  4 snd_intel8x0,snd_ac97_codec,snd_usb_audio,snd_pcm_oss
snd_hwdep              13125  1 snd_usb_audio
snd_timer              24901  2 snd_seq,snd_pcm
snd                    53317  17 snd_mpu401,snd_mpu401_uart,snd_intel8x0,snd_ac97_codec,snd_usb_audio,snd_seq,snd_rawmidi,snd_pcm_oss,snd_mixer_oss,snd_seq_device,snd_pcm,snd_hwdep,snd_timer
soundcore              11681  1 snd
snd_page_alloc         14281  2 snd_intel8x0,snd_pcm
and

Code:
>> lspci | grep audio
00:1f.5 Multimedia audio controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 02)
so I think everything is still being detected but alsa is not being loaded. I don't have /etc/init.d/alsasound or /etc/rc.d/init.d/alsasound so I don't know if there is another service to restart or what.

I'm using Fedora Core 8.

Any help would be great.

Brian

Unhappy

me again.

I've been finding this
http://home.nyc.rr.com/computertaijutsu/rhsound.html
resource useful.

And now I think my modprobe.conf is messed up:

Code:
>> cat /etc/modprobe.conf
alias scsi_hostadapter sata_promise
alias snd-card-0 snd-intel8x0
options snd-card-0 index=0  
options snd-intel8x0 index=0  
remove snd-intel8x0 { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-intel8x0
alias usb-controller ehci-hcd
alias usb-controller1 uhci-hcd

#----cut here----
# I2C module options
alias char-major-89 i2c-dev
alias eth0 e1000
alias snd-card-1 snd-mpu401
options snd-card-1 index=1  
options snd-mpu401 index=1  
remove snd-mpu401 { /usr/sbin/alsactl store 1 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-mpu401
does this mean my modprobe.conf is removing these sound devices?

please help.

I guess my usb microphone was taking priority and I had to add

options snd-usb-audio index=-2

to the modeprobe.conf.

So problem solved. Sorry for clogging the forums with my solo-conversation. I should have waited a few more minutes before posting.

thanks anyways. I love linux
