no sound via HDMI with Intel soundcard

A monitor is connected to a computer with an Intel soundcard

via display port.

The Monitor (OSD) shows: Audio Input is DiplayPort

[c]$ aplay -l[/c]

lists three HDMI devices

[c]$ speaker-test -D hw:0,7 -c 2 -t sine[/c]

starts alternating output to left and right speaker,

but no sound is to be heard.

With the same command on SliTaz next from 2017-06-16 with

kernel 4.9.30, sound can be heard.

Is kernel 3.16.55 configured unsuitable for HDMI sound output?

Or is something else (alsa, drivers) improperly configured?

Re: no sound via HDMI with Intel soundcard

For what it's worth, I've recently encountered some issues with firmware and some kernels reversing peripherals.

One solution was to download the firmware https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git

the other was to sweep the audio devices with asoundconf

Per quel che può valere, recentemente ho riscontrato alcuni problemi con il firmware e con alcuni kernel che invertono le periferiche.

Una soluzione è stata di scaricare il firmware https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git

l'altra di sweppare le pericheriche audio con asoundconf.rc.
