1. User’s Manual — Music Player Daemon 0.22 documentation
2. AFIK M.A.L.P is a MPD controller under development; MPDROID isn't.
3. I don't know. I prefer the newest version (less bugs, more new features)

Hi bern,

Setting dai_format or serconfig is not supported since I dropped the related code (only playback of both I2S as well as DSD is supported, no SPDIF) with standard dai format setting as appropriate for a Cronus or similar configuration.

If you have such a standard configuration this should work regardless of the dai_format / serconfig parameters.

Should I install something?

Sorry, cannot be of much assistance here... Are the headers indeed installed in '/usr/src/linux-headers-4.19.79+'? Could it be that lirc_bbb is not compatible with the 4.19 kernel for some reason? If you install the headers of the standard buster kernel, does it work?

Thanks for replay.
That's a pity since some users (including me) use Cronus and Right Justified Data Format 'dai_format=16386' (instead of default 16385). Could you consider to restore this parameter as variable in one of the next releases?

I don't know. I tried to build GitHub - miero/lirc-bbb: LIRC driver for BeagleBone Black module several times with previous kernels add it worked.

I have to check. I'm sure it worked with 'Linux beaglebone 4.8.13-botic7-rc3 #1 PREEMPT Sat Dec 10 01:35:51 CET 2016 armv7l GNU/Linux'

I just updated the debian-buster branch and this parameter is again enabled. Please try whether right justified works fine for you now.

Can you try to directly call

make build

and skip the prepare step?

Thank you!
I'm just checking out BBB debian kernel and going to build new one but this time I try to compile kernel directly on BBB machine (will take few hours). Last time I cross compiled BBB kernel on my home X64 Ubuntu server 19.10 machine.

make build

I will try when I have a new kernel. Let's keep our fingers crossed for successful kernel and module build

It took 15h to bulid BBB kernal on BBB machine.
After installing new kernel dai_format paramater (in my case Right Justified data format) works properly.

One strange think I encounter is lack of automatic shutdown after plug out the mains when using battery attached to Hermes (about battery see the end of the first post of Hermes thread). Before installing new kernel when I plug out the mains Debian automatically switch off in few seconds . It currently doesn't work. System still running discharging batterry. How could I fix this?

It doesn't help much. Still lack of some files in headers directory:

Functionality extension in micro audiorender (beta):

1. New audio renders of the LMS and AirPlay protocols have been added.
2. Added support for wpa WFi.

Linux kernel remains the same - 4.9.146-Botic7-rt

I abandoned the code for powering down on battery automatically. For my BBBW use case I found that simply hard power down (without taking care of proper shutdown) does not cause any issues so I do not have any battery and also I often do not shut down properly before removing power.
If you want to have this functionality on more recent kernels, you can have a look and port this patch yourself: linux-dev/0013-pm-shutdown-on-power-button-press-or-power-loss.patch at botic7-v48 * miero/linux-dev * GitHub

With regards to the module compilation: Maybe try with the default buster kernel. If this leads to the same problems, then probably the outdated code of the lirc-bbb module is to blame. If it works then we need to further investigate how the kernel headers are built for the boticized kernel.
