Unable to get sound using official RPi RT-Kernel

Hello. I installed the official 4.14.74-rt44-v7+ Realtime Kernel on my Rpi3. Everything appears to be loading correctly, the driver shows up in lsmod, but I am getting no sound, and after a few minutes, Fluidsynth reports an audio I/O error.

Output of lsmod:

Code: Select all

snd_soc_core          184320  3 snd_soc_wm8731,snd_soc_bcm2835_i2s,snd_soc_audioinjector_pi_soundcard
snd_pcm                98304  5 snd_soc_wm8731,snd_pcm_dmaengine,snd_soc_bcm2835_i2s,snd_soc_core,snd_soc_audioinjector_pi_soundcard
and the output of uname -a

Code: Select all

Linux raspberrypi 4.14.74-rt44-v7+ #1 SMP PREEMPT RT Wed Nov 14 01:31:00 EST 2018 armv7l GNU/Linux
Any help with this would be greatly appreciated.
