To be clear: this fix hasn't been all sunshine and rainbows. It seems that there's a randomly probability at bootup that some of the pins don't connect right and I only get L,R,RR or some weird variation of this. Sometimes power cycling the system eventually corrects this to get at least 5 of the 5.1 channels. The bass redirect seems to pass things to LFE, but LFE as a discrete channel doesn't really seem happen very often for some reason.
And even weird, mythtv (using the ALSA support), I have to select surround50 as the device or the channels get mismapped. Running hdajackretask seems to _completely_ screw things up, so that's a no go. Maybe a kernel/ALSA dev can chime in and maybe have a rough idea of what's happening? I assume the powercycling reloads the firmware on the DSP, and something during that initialization kind of haphazardly maps pins. I've never booted this system into windows to know if that would have any real side effects. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1261211 Title: No multichannel support on Creative CA0132 Status in ALSA driver: Confirmed Status in alsa-driver package in Ubuntu: Won't Fix Bug description: Multichannel sound is not working on my Creative CA0132 sound card.
