Takashi Michal and Takashi, I've been researching your issue this morning. I just noticed that your exchange had ensued. I configured my AD1986-based system as closely as I could to match your AD1985 mixer settings. In doing so, I experienced results similar to what I'm assuming you described: Only front channel sound came out of the surround and c/lfe jacks. Here is what I had to change to get the appropriate multichannel sound: 1) The command "speaker-test -c6" does not work on my system. I have to use "speaker-test -Dsurround51 -c6" (Perhaps this is related to running an old version of speaker-test.) 2) I disabled "Spread Front to Surround and Center/LFE" The explanation for 2) is this: There can be only one source for each of the Surround and Center/LFE jacks active at one time. When "Spread Front to Surround and Center/LFE" is disabled, the surround channels go to the the jacks; when this control is enabled, ONLY the front channels go to the surround and c/lfe jacks. Considering the register values Michal provided and Takashi's patch: The logic of the code is as follows: (Slightly simplifying,) functions is_shared_linein() and is_shared_micin() return TRUE if the mixer is configured for shared jacks AND NOT for 6 channel mode. In this case it is appropriate to set these bits (LODIS and CLDIS). Yep. So, can you confirm that my fix is OK? Then I'll queue it up to ALSA tree. thanks, Takashi Takashi, I need to think this through before I can confirm. Something doesn't seem right. Let me figure out why I wrote ad1986_update_jacks() to be so different from ad1888_update_jacks(). I'll keep you posted.
