Watchdog reboot after Ctrl-C of aplay

[roelfdiedericks]

Using kernel 5.15.114, and DTS as per the examples on a MT7628AN by Hilink on OpenWRT 22

Board i'm using is a waveshare Audio HAT https://www.waveshare.com/wiki/WM8960_Audio_HAT and I'm using the HAT's refclk, so no refclk defined in the DTS

When playing a 16 bit 48k wav file through aplay, and the process is interrupted, e.g. using Ctrl-C or SIGNIT the board hangs and eventually the watchdog timer reboots the board.

Tried various things such as https://forum.openwrt.org/t/i2s-freezing-on-mt7628/81140/2 but still having the same issue

There's no kernel output or anything, just the watchdog reset message.

An ideas?

Apologies, here's the relevant DTS config.

codec: wm8960@1a {
compatible = "wlf,wm8960";
reg = <0x1a>;
wlf,shared-lrclk;
wlf,hp-cfg = <0 0 0>;
wlf,gpio-cfg = <1 0>;
};

I also sometimes get the following output from aplay before it hangs

aplay piano2.wav
