I/O errors when I open Kodi while an audio CD is inserted

Strangiato · 2025-05-05 03:42:18

Hello

I use Arch with KDE Plasma, my system is fully updated.
When I open Kodi while an audio CD is inserted, kernel log reports errors:

I can reproduce these i/o errors with two audio CDs.
When I try to play the CD, Kodi hangs for a few minutes saying "Fetching CD information", then a list of discs shows up, I choose an option from it and finally the audio CD plays.
Any idea on why these i/o errors occur, and how to stop them?

Thanks for reading.

"AU·DI·O-C·D"?
What's that?

I suspect kodi is trying to get the cddb information.
1. does

cd-info --no-header --no-disc-mode --no-device-info -I -T --cddb-server="gnudb.gnudb.org"

trigger the same?
https://archlinux.org/packages/extra/x86_64/libcdio/
2. does

mpv --geometry=360x120-64+32 --video-unscaled=yes --force-window=yes "cdda://2"

? (and does it play your possibly less-than-redbook compliant disc?)

Strangiato · 2025-05-05 13:43:13

The first command gets stuck for a few minutes and then says:

cd-info --no-header --no-disc-mode --no-device-info -I -T --cddb-server="gnudb.gnudb.org"
CD location   : /dev/cdrom
CD driver name: GNU/Linux
   access mode: IOCTL

The second command does not play the cd and says:

$ mpv --geometry=360x120-64+32 --video-unscaled=yes --force-window=yes "cdda://2"
++ WARN: Can't get file status for 2:

mpv --geometry=360x120-64+32 --video-unscaled=yes --force-window=yes "cdda://" --start='#4'

(cdda://2 is bad syntax and tries to use "2" as sr0 device, sorry - it's been a minute )

mpv produces no error in the kernel log and plays the disc as expected.

seth · 2025-05-05 14:15:33

Can you also just play starting at track #0?

mpv --geometry=360x120-64+32 --video-unscaled=yes --force-window=yes "cdda://"

Unfortunately it doesn't seem to be possible to disable cddb queries w/ kodi, are those commercial discs which might or not use some copy protection stuff?

Strangiato · 2025-05-05 14:19:42

Yes, the disc plays. It's a commercial disc without copy protection.

Edit:
I have just disabled cddb queries in Kodi settings, but the errors in the kernel log persist.

cd-info -C /dev/sr0 -I -T --cddb-server="gnudb.gnudb.org"

And I assume that call will also trigger those errors?

No error in the kernel log this time.

seth · 2025-05-05 14:36:27

'key so the cddb query doesn't trigger it either (did you get meaningful cddb data from this, btw?)

Seems to have been caused by trying to control the drives speed?

Strangiato · 2025-05-05 14:38:53

I have never done any speed control with my drive.

seth · 2025-05-05 14:43:21

The suspicion would be that kodi does (nb the thread was from 2010)
