Have 2 DACs, can play to either HW:1,0 or HW 0,0 but not both together (in music player tab). How do I define a second output and enable both?That might require a UI update I believe. I'm working on getting Pi4 to work with Gear Isolation right now. Will look into this once I get that done. Remind me if I forget :p.

Point me in the right direction and I should be able to do things.Look under /var/www/players/mpd-022/mpd.template (or mpd.conf.template). Modify the file as needed, restart MPD and see how it goes. Note that right now this config file will be overwritten next time you apply an update. I'll add the feature to modify the file from the webapp in a future update.

I managed to edit the mpd.conf.template file to create 2 ALSA outputs and got music to deliver to both DACs simultaneously.(24-Feb-2021, 05:56 PM)Snoopy8 Wrote: If it is easier, I can go under and create the config file entries.

Curious, are the 2 DAC's in sync? Now sure how to easily measure this, I'm sure they've drifted, and there'll be jitter. Some audio cards (or DACs) have the ability to sync to a master clock (most pro gear will have this)..

Will do a write-up once I have implemented it in a few weeks time.(25-Feb-2021, 07:38 PM)Snoopy8 Wrote: Thank you.

Yes, if using standard USB ports, will get drift. Am using an external USB card that has 2 USB ports, driven by a master clock. One will drive my system, second one will drive dual subs which is optimised by MSO (uses subs to "fill troughs" in the bass response of mains). Question: is there an equivalent config for LMS to do dual simultaneous output?

(Example) That's the way I'm going to do this in the future. It's kind of weird, although there're lots of progress made in the past 2+ months, why do I still have the feeling there's still tons of things to do? ![]() ![]() RE: MPD Pipe output - Snoopy8 - 26-Feb-2021 (26-Feb-2021, 12:41 PM)agent_kith Wrote:(26-Feb-2021, 12:32 PM)Snoopy8 Wrote: Question: is there an equivalent config for LMS to do dual simultaneous output?Easiest way is to create a new ALSA device and "chain" it to your two DACs. (Example) I was anticipating having to do it that way originally. It is easier within Mpd to define 2 audio outputs in template and it is done. The following comments have not yet been tested, but I think:
RE: MPD Pipe output - Snoopy8 - 21-Mar-2021 Have now updated the Wiki on MPD Dual Outputs https://www.snakeoil-os.net/wiki/Players/musicpd#Dual_outputs Confirming that this method allows dual DSD outputs and can be used in LMS running upmpdcli as the client. |
