The audio device you have connected doesn't support AC3/DTS, only stereo PC=
M.
So yes, you would hear audio because the audio test will only try stereo.
Here you're trying to play AC3 which your audio device (TV) doesn't support=
.
You have configured your machine and enable AC3/DTS passthrough.
Uncheck those. Keep audio as Stereo.

As you're running a very recent version of ALSA, you can see what your
audio device supports in the help description at the bottom of the
screen when you move the cursor to the audio device name (here
ALSA:hdmi:blah

If you believe your TV does support AC3/DTS (which would be very
surprising but who knows...)

It could be a problem I've seen with very recent version of ALSA if at
any time you put your PC to sleep and turned it back on before the TV
was on. The ELD value isn't read properly and ALSA disable some audio
options

Try rebooting your PC, making sure the TV/amplifier is on before the PC reb=
oot.
