Video freezing every 3 minutes on Ubuntu 22.04 on Acer R11 Chromebook

in flag

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?

Can you check if there has been any ususual entries in `journalctl -r` right at the moment when the video froze? Also, how much RAM do you have?

There doesn't seem to be any entries right at the failure, but when firefox starts I get two suspicious entries.

Both entries contain ALSA Lib: one ends with Uknown SEQ default, the other with Cannot access file /usr/share/alsa/alsa.conf. Machine has 4 GB memory

Can you edit the question and add the exact error message? I had a different issue (https://askubuntu.com/q/1451125/124466) in another chromebook, and found a solution by google searching the exact error message

I tried the solution from the link you provided. It seems to fix the issue when streaming video with firefox (which is great-thanks!), but playback of stored video with vlc has audio drop-outs every few seconds.

Using firefox to play a stored video file seems to be fine.

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.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
