Converted Acer R11 Chromebox to Ubuntu 22.04 using mrchromebox.tech/#fwscript UEFI firmware replacement. Everything works fine except any video player (firefox, vlc) freezes video about every 3 minutes. Clicking on pause and waiting a few minutes then clicking play allows the video to resume, only to freeze again after about 3 minutes. The Acer R11 (C738T Cyan) uses an Intel Celeron N3150, Mesa Intel HD Graphics 400. Any known fixes for this?

This is a partial answer, provided in the link by Archisman Panigrahi in the comments. It fixes (so far) the video freezing issue using firefox, but causes erratic video in vlc (hence the partial answer).
edit /etc/modprobe.d/alsa-base.conf
and add the line
options snd-intel-dspcfg dsp-driver=2
reboot.
