Kernel Issue with Sparky+Kali+Piano 2.1 setup

[Cprogrammer]

I have been playing with the DAC for the past 2-3 days. Once in a while when I change the song (I am using MPD), I suddenly starting getting loud hissing kind of noise. After that whatever song I play, I get the noise. It gets solved only by rebooting the box. I checked the journal logs and this is what I see each time the problem happens. In one of the cases the song played at some weird speed. I have tried alsa init command. Nothing seems to help. As a last resort I have now loaded DietPi_SparkySBC-ARMv7-Stretch_AlloGUI image and updated it to the latest version available.

Current version : v6.19.6

My Music directory is mounted using NFS in /etc/fstab

 

This is the journalctl log. Has anyone observed this and fixed it?
