Title:
[XPS 13 7390 2-in-1, Intel Icelake HDMI, Digital Out, HDMI] sound
rarely works
Status in linux package in Ubuntu:
Confirmed
Bug description:
I have an Ice Lake laptop (Dell 7390 2-in-one) which I am connecting
to a TV over HDMI via a Novoo USB-C multiport adapter. This is not a
Thunderbolt device, it is just USB-C.
It seemed like things used to work fine before I upgraded this system
from Ubuntu 19.10 to 20.04, although I couldn't say for certain at
this point. But I'm having a ton of difficulty getting audio output
over HDMI. Getting it to work requires a lot of retries to
reinitialize the device (either by suspending/resuming the laptop, or
plugging/unplugging the HDMI cable and/or the multiport adapter). It
does work sometimes, but my success rate is very low at this point.
Even when it does work, it's brittle: any change to the output port
(to speaker and back to HDMI, or from stereo to surround and back)
will often break the audio. This fact seems to suggest that the
problem doesn't have anything to do with the low-level initialization
of the HDMI port; I'd be looking at some mid-layer code.
To be clear, there doesn't seem to be any particular symptom, or
anything of interest in the logs, other than an absence of sound
output.
