Are you having problems with multiple sound in FC4 ? Look at this !

Greetings from Brazil
Here's how i managed to solve my problems with sound in fedora core 4 ...

first edit the /etc/asound.conf ... it sould look something like this:

#beginnig of asound.conf
pcm.asymed {
type asym
playback.pcm "dmix"
capture.pcm "dsnoop"
}
pcm.!default {
type plug
slave.pcm "asymed"
}
pcm.!dmix {
type dmix
ipc_key 5678293
ipc_key_add_uid yes
slave {
pcm "hw:0,0"
period_time 0
period_size 128
buffer_size 2048
format S16_LE
rate 48000
}
}
pcm.!dsnoop {
type dsnoop
ipc_key 5778293
ipc_key_add_uid yes
slave {
pcm "hw:0,0"
period_time 0
period_size 128
buffer_size 2048
format S16_LE
rate 48000
}
}
#end of asound.conf

now, i have skype, xmms, xine player, gaim, and some other programs all working perfectly with sound ....
skype demmands that the buffer size be 2048, i 've tried other settings but it wouldn't work ... so if you use skype i suggets you leave the buffer size at 2048 and the Period size at 128 .... You should start skype with alsa like this: "aoss skype"

With xmms you'll need the xmms-alsa plugin and configure it to use the same settings in the asound.conf ... Buffer time = 2048 and Perido time = 128 and disable Mmap, this is done in the advanced tab in the alsa-plugins configuration.

Like skype all others applications that require sound sould be started trhough alsa: "aoss <app>".

Well, i hope this helps ....

See ya !!!

Does this solve the problem of not being able to play sound files from different players at once? Because I cant play files from noatun and xmms at the same time. thanks.

yes, it should ..... i can use xmms, skype, xine or any other sound app, that uses alsa, at the same time ...

Allright. Thanks faustoandrade, I'll put this one to work. Cheers!

I doesn't work for me. I have updated FC4 now, and in /etc/asound.conf there are the following lines which are completely different from the above ones:

#Generated by system-config-soundcard, do not edit by hand
#SWCONF
#DEV 0
defaults.pcm.card 0 
defaults.pcm.device 0 
defaults.ctl.card 0

Any hints?

Thanks in advance!

Thats exactly the same asound.conf I have and the mic never works with Skype. When I try yoo call I get a red phone
All other playback type programs (ex: XMMS, Amarok, XINE) work fine. All line and mic's are enabled in ALSA. If you figure this out let me know. Thanks

Does your microphone however work? I have no problem with my microphone, I even use two of them, because my sound card has a 2nd plug in the front of the computer box. Maybe your's have 2 also, and you should select the Mic 2, from the list in the volume preferences. My problem s rather with the playback. When I listen to music, I can't use nor skype, nor a webpage with flash in it, because they can't reach the sound output

[grndplane]

I have never tried to record with the mic. Is there a program or a test I could try? I have the kicker applet for alsa turned on and everything is cranked up. Thanks

[grndplane]

OK here is a bit more information. When I log on as root and use the Kmixer, I can enable the mic and the 20db boost. Then crank up all the controls and start Skype. I can call the Echo/Test and I can barely here myself talk, but I get no errors and it appears to work with the exception of low mic volume. When I log on as regular user and start Skype and try the Echo/Test it says problem with sound system. The Kmixer is set the same, and all other play back programs work fine. I think it is a permission thing again, and I have disabled just about everything on this system(ex: firewall, seclinux, and set permissions to everything to all users. Where do look next? Thanks

[grndplane]

Now sound only works in root. The other 5 users can not play sound. I do not see anyplace in root to give sound permissions to other, or all users. Where do I go from here. Thanks
