RealtimePi 0.5.0 RC1 status

[guysoft]

Hey all, Dues to lack of maintenance by the Rpi realtime linux branch, and since @kdoren got a 5.10.y tree working, I am release this release candidate. I tested it and it boots with RT kernel on a RaspberryPi 4B here I have.

pi@realtimepi:~ $ uname -a
Linux realtimepi 5.10.35-rt39-v7l+ #8 SMP PREEMPT_RT Mon May 24 16:06:59 PDT 2021 armv7l GNU/Linux

• New raspberrypi kernel 5.10.35-rt39-v7l+

Hi, I have tested the latest nightly build and mostly everything is working, except I can't get my AudioInjector Zero to work. If I use the 2021-06-10 build, it works, but seems to give a lot of xruns in MOD-UI. Are there any major differences between the 2021-06-10 and 2021-06-15 build?

@micahvdm The build is different because the source code for the kernel is different. Unfortunately I haven no way to test this and let alone fix it. @kdoren might know what is missing.

[kdoren]

@micahvdm nothing should be missing. According to: https://github.com/Audio-Injector/stereo-and-zero in /boot/config.txt, you'll need: dtoverlay=audioinjector-wm8731-audio Also: "Don't forget to enable the output HiFi mixer using alsamixer or this on the commandline : amixer set 'Output Mixer HiFi' on"
