WASAPI EVENT audio channel does not respond to volume change in EarTrumpet

[philipdharris1]

I use Foobar2000 as my music source
I have the output device to be WASAPI

However, the volume control for the WASPI channel doesn't affect anything. I can still receive sound from foobar2k

OS: Win 10 Pro
Build: 14393.2189

On further inspection, it appear that Windows itself grabs WASAPI as the program.
Probably not a fault with EarTumpet

Yeah was about to say, based on your description, changing the controller volume changes the programs volume, not the speaker's volume itself

The EarTrumpet control should still get a list of all the programs running and adjust them individually. If anything, both Foobar2k AND the WASAPI service should be shown. For example, I can go into Foobar and manually change the volume.

how does EarTrumpet get a list of running programs?

@riverar will be able to answer this better, but EarTrumpet doesn't retrieve a list of running programs, we access the list of current audio devices and the audio sessions for those devices.

I took a look at Foobar2000 with that custom component installed and it appears to cause a bunch of other issues (at least, on my system, including crashing YouTube in Chrome when I started trying to play audio from Foobar) but it does appear the volume for Foobar is not controllable when using WASAPI as it seems to partially bypass the Windows Audio Service and talks directly to your audio driver.

The built in Foobar outputs appear to work fine with EarTrumpet 2.0.

I can control foobar volume within the program itself when in WASAPI mode

when you say built in, do you mean DirectSound to the windows controller?

@philipdharris1 This plugin configures foobar2000 to play in exclusive mode. That is, it takes over the playback device and prevents other apps from playing audio and disables all controls.

You may want to email the plugin author. There's nothing for us to fix here, sorry!
