Hello #audio #engineering bubble!

I'm searching a way to change volume on a 5.1 #spdif signal by digital means (aka: serial, spi, network, ...)

Can be a device i could buy, but i'm also not afraid of soldering if necessary.

Anyone got some pointets for me?

Configuring Ubuntu for 3.1 surround sound output #sound #alsa #hdmi #spdif

I've learnt that #TOSLINK and S/PDIF while #digital don't provide the same bandwidth for #audio than #HDMI 1.0. It feels weird though to connect any non-video media player to my #amp through... HDMI. Is there some digital standard that basically is HDMI sans #video?

This would be especially useful since while my amp does have HDMI input it is a bit... picky and despite pass-through enabled it reduces the video quality to FHD only in a setup like [source]->[amp]->[sink]. So currently I'm splitting the HDMI into video (HDMI again) and audio (TOSLINK or S/PDIF) and feed only the latter to the amp.

I acknowledge that the difference b/w S/PDIF and HDMI audio is probably not audible to me, but it annoys me in great detail nonetheless, that there seems to be no non-video connector for digital audio on par of HDMI. I wonder when we'll be connecting computer speakers to the PC via HDMI...

@ephemeris certainly.
But, since OpenBSD 6.7, it's sndioctl than manage audio on… and others controls,
and not anymore audioctl and mixerctl.

FYI: yes my user is part of operator group.

On azalia manpage, I can't figure out what is supposed to be "the mixer class". I see the dig.dac for the "widget type" to use SPDIF output.
But I do not understand how to use it and where?

May be some can help me to configure an SPDIF output for azalia0 on OpenBSD 7.2?!
