Comment 29 for bug 303679

Same problem here, Ubuntu 10.10 - 64 running on AMD x 2 - Asus M2N4-SLI with integrated soundcard and CA0106 Soundblaster.

Both cards worked fine but after an upgrade the CA0106 was unable to play sound.

Solution: Install graphical ALSA mixer - gamix - and unmute the "IEC958 Playback" for "Audigy SE [SB0570]: CA0106"

Is located at the top left, second control, easy to find as is the only checkbox there, no slider at that field.
