If I understand correctly, you have three DACs, one internal speaker, one headphone jack, and three jacks that are both used for 5.1 surround and line out/mic/line in. Is this correct?
This is correct. In addition I have a front mic jack.
How do the DACs get assigned in this case? One would assume that you'd get 02 -> Front LO, HP, Speaker, 03 -> Rear LO, 04 -> CLFE LO.
With my private patch to enforce multi-io I seem to lose the internal speaker which isn't bad because it isn't connected (and probably never won't be).
You are right concerning the remaining assignments:
multi_outs = 14/0/0/0 : 2/3/4/0 (type LO) out path: depth=3 '02:0c:14' multi_ios(2) = 1a/18 : 3/4 mio path: depth=3 '03:0d:1a' mio path: depth=3 '04:0e:18' hp_outs = 1b/0/0/0 : 2/0/0/0 hp path: depth=3 '02:0c:1b' spk_outs = 15/0/0/0 : 0/0/0/0
And then the volume/mute control for DAC node 02 would be called "PCM" (since both hp_lo_shared and spk_lo_shared are true), but in fact it would be more appropriate to call it "Front".
I've got a Master that would only affect the Front (PCM) and a PCM that affected Surround/CLFE which was very unpleasant.
With the patch I'm getting a real Master (for all Front/Surround/CLFE) and a separate Front Volume Control in addition to Surround, Center and LFE which is exactly how it should be.
Anyhow, I'd say that the typical case where we want the "Headphone+LO" names is where we have only one LO, and then multiout.num_dacs would be 1, not 2. (I think, it was a while since I looked into that part of the driver...)
I'm fine with everything below 3. :-) Just tell me.
