Hello everyone,

I have Audigy sound card (c-media sb 8738 5.1 channel (CMI8738/PCI-6ch-LX)) on my gentoo computer.

lspci | grep audio
08:00.0 Multimedia audio controller: Creative Labs SB Audigy LS

I've got my sound card working through a couple of speakers but still struggling with 5.1 and microphone.

Any info, input would be appreciated.

Have you checked alsamixer to see if they are mutted? From a terminal type alsamixer use the left & right arrow keys to navigate the Up & down arrow keys for raising or lowering the volume the m key to mute or unmute then Esc to exit.

I re-emerged alsa-plugins with oss and pulseaudio flags enablad. Now I can hear myself when I speak in microphone through speakers but I can't recoder sound using sound recoder and audacity programms. Sound capture in skype doesn't work too.

I've chanched in alsamixer:
Analog S to Mic
Digital to i2s in
Shared to Mic in
I won a microphone but I continue strugle with 5.1 I think for this I need pulseaudio server.

I have the same idea with you. Great! Thanks for sharing.
Glad to hear you're using this: I plan to keep it much more aggressively up-to-date than has been the case in the past, but don't hesitate to let me know if you find errors or need clarifications.
