[SOLVED] No Audio and Video wont play when sound is on

[ssalanski]

I'm having an intermittent issue with media playback, where I am unable to get any sound from any application (including audio settings), and videos do not play unless they are muted. This happens for streaming videos (eg youtube) as well as local mp4 files.

It seems like this user posted with the same problem I'm having: viewtopic.php?t=402535
That thread closed with the solution being a restart, and while this does sometimes resolve the issue for me, it's about 50/50, and I don't really consider this a long term fix for the problem. The issue is sometimes present immediately after restarting, other times it arises after waking the machine from sleep. It seems to be a problem more frequently when I am using a USB-C dock that connects to two external monitors, but that might not be related, it's hard to tell.

I have tried booting with an older linux kernel, as well as changing graphics driver versions around.

Welcome to the forum, ssalanski.

According to Dell, the latest BIOS/UEFI is version 1.28.0 so your system is missing all of the updates.

Machine: Type: Laptop System: Dell product: Precision 5550 v: N/A serial: <filter> Chassis:
type: 10 serial: <filter>
Mobo: Dell model: 06G3G6 v: A03 serial: <filter> UEFI: Dell v: 1.6.1 date: 12/24/2020

Version 1.21.0 and Version 1.9.1 both indicate they "Improved the stability of the system."
Version 1.19.0 indicates, "Fixed the issue where an error is displayed when you stream Netflix in 4K resolution."

There are also a number of dock fixes mentioned in the updates.

10th-gen Intel came out long after the first release of Linux Mint 20 versions so it's possible upgrading to a newer version (which would have many more newer packages than just the kernel) may help.

Code: Select all

[   20.626698] snd_hda_intel 0000:00:1f.3: refused to change power state from D3hot to D0
[   20.747733] snd_hda_intel 0000:00:1f.3: CORB reset timeout#2, CORBRP = 65535

If BIOS update and trying kernel 6.5 doesn't fix it, try disabling the sound card power saving with the following command (and then rebooting):

Code: Select all

echo "options snd_hda_intel power_save=0" | sudo tee /etc/modprobe.d/fixsound.conf

If the fix doesn't help or causes issues, you can undo it by simply deleting the file it creates (and rebooting):

Code: Select all

sudo rm /etc/modprobe.d/fixsound.conf

...trying kernel 6.5 doesn't fix it...

OP is not yet running a Linux Mint 21 version so 6.5 is not available to them.
(I nearly typed the same suggestion before noticing they were on LM20.2. )

I recently updated to Mint 21.3 (still Cinnamon), though I remain on Kernel version 5 (currently 5.15.0-122). I have not experienced the issue since.
