jackd fails to work on Raspberry Pi & HiFiBerry DAC+ ADC Pro
Describe the bug
I'm trying to start jackd as:
jackd -dalsa -dhw:sndrpihifiberry -r96000 -p128 -o2 -i2
This successfully starts jackd with the following log:
pi@rpi:~ $ jackd -dalsa -dhw:sndrpihifiberry -r96000 -p128 -o2 -i2

However, as soon as I try to connect the first client, the client hangs for a few seconds and then this happens:

Environment
Following setup:
- RPi 3B+ and RPi 5
- RPiOS,
Linux rpi 6.1.0-rpi7-rpi-2712 #1 SMP PREEMPT Debian 1:6.1.63-1+rpt1 (2023-11-24) aarch64 GNU/Linux - HiFiBerry board with PCM1863 ADC and PCM5122 DAC
- Only ALSA audio card in the system, i.e.
aplay -l && arecord -lonly lists that single card - ALSA driver works correctly, i.e.
arecord -f S32_LE -r 96000 -c 2 -d 5 "test"; sleep 1; aplay "test"records and plays back a wave
- JACK Version:
jackdmp version 1.9.21 tmpdir /dev/shm protocol 9 - Installation: Tried both the Debian/RPiOS package and compiling the latest master
Steps To Reproduce
Install latest RPiOS, configure card as described here. Install jack. Mask all PulseAudio/Pipewire/etc systemd units. Reboot. Start jackd with command provided above. Start any client.
Expected vs. actual behavior
Error message not printed, audio system working.
Further info
I can try out stuff and recompile jack comfortably. I'm happy to put in some time to help getting to the bottom of this.
Uhm, might this have something to do with this commit from just a couple days ago? I'll compile, run, and report back
