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.
Regards,
Christian

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?
Code:
debian@beaglebone:/usr/src/linux-headers-4.19.79+$ ls
Documentation Makefile arch certs drivers fs init kernel mm samples security tools virt
Kconfig Module.symvers block crypto firmware include ipc lib net scripts sound usrI 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.
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.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:

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.

Unfortunately I do not have sufficient skills. I'm no programmer or coder.
I installed the newest image 'BBB-blank-debian-10.2-console-armhf-2019-12-02-1gb.img' which I could found in Index of /rootfs/bb.org/testing/2019-12-02/buster-console
The kernel is:

How do i config alsa so it sees the Botic device as multichannel?! I have MMMM in serconfig but aplay sees only two.
/etc/asound.conf is pretty much default, but the board does see a USB multichannel DAC as really multichannel if plugged in.
Thank you!

You might just want to try out what you can achieve. This is diy 🙂 Apparently there is also a (in my view much simpler) solution using some python scripting retrieving the status of the PMIC (see discussion in batteries - How can I power Beagle Bone Black with 3.7V LiPo? - Electrical Engineering Stack Exchange).
I believe that is a sign that the code of lirc-bbb needs updating to ensure that it is still possible to build it using newer kernel versions.
Not sure what you are trying to accomplish but if you want ‘aplay’ to output multiple channels then use the -c flag followed by the number of channels. If you are more specific about what you want ALSA to do (you can’t assume much...) it may become a question of tweaking /etc/asound.conf
Frank
There is squeezelite missing command string,I tried run /usr/bin/squeezelite -D delay : u32le,and it can output native DSD and work prefect . But I still cannot let command string run correctly at /etc/init.d/S99squeezelite and /etc/rc.botic/S99squeezelite !
Frank, thank you for replying. I just say that aplay -l or -L sees only two channels instead of 8 expected by serconfig.
Is this normal to force channel number in alsa config? An external USB multichannel DAC looks initially as a device with 8 outs. Me stupid?
The etc/asound.config file is very basic in the ‘stock’ distribution of Botic. I am traveling currently but when back with my home system l will reply again with some additions for asound.conf that you can use to open more channels and manage signal routing within them. Shoot a reminder if you don’t see something next week. 🙂
