[SOLVED]Single application not playing audio through HDMI

I'm trying to play Stepmania (git version, self compiled) through my tv since I got a pad lately, only to find that the audio keeps playing through my shitty laptop speakers. Every other application I try uses the TV speakers correctly.

Trying to figure what was going on I tried looking for it on pavucontrol while running, only to not find it anywhere. It also doesn't show up on the Plasma volume applet, settings manager nor on EasyEffects output list.

Running it through console I get

./stepmania

any idea of what's happening? Running pipewire, packages up to date.

Re: [SOLVED]Single application not playing audio through HDMI

It seems to enforce plughw:1.0 on an alsa level which is equivalent to direct device access and will not show up on the pipewire daemon

According to the upstream sources this should support pulseaudio, check your build log whether you missed compiling pulse support in (or rather the build system not recognizing libpulse for some reason), and if you didn't and it's present change it's preferences and switch the sounddriver to "pulse" or switch the ALSA device to "default" and have pipewire-alsa installed. https://github.com/stepmania/stepmania/ … references

Yep, preferences.ini was at fault.

SoundDrivers=pulse

Marking as solved, should have looked it there 1st.
