Comment 1 Paul Menzel 2019-02-08 16:11:35 UTC

This still happens with Linux 4.19.19.

Comment 2 Jean Delvare 2019-08-28 09:10:18 UTC

I see the same error messages on a Dell Optiplex 9020 with an AMD Radeon R5 240 (Oland), when my Dell 24" display is connected with a DisplayPort cable. I do not have the errors when connected with a DVI or VGA cable.

Comment 3 Jean Delvare 2019-08-28 09:29:55 UTC

Error -2 is ENOENT (No such file or directory). The driver queries the display for audio-related information, while my display does not have speakers nor headset connector.

Paul, can you confirm that you are also using a DisplayPort cable and that your display does not have speakers?

I suspect that the "error" is pretty much expected in this case and the driver is being too verbose about it. Either the calling code should consider -ENOENT as a non-error, or the helper functions should simply return 0 when no audio-related data is available from the display.

Comment 4 Paul Menzel 2019-08-28 09:41:48 UTC

I confirm, that the Dell monitors used here, do not have speakers.
