I was doing some testing with Tex Murphy: Mean Streets, and using different DOSBox versions i realized that this game sound is broken in DOSBox ECE.
I have the GOG version, that comes bundled with DOSBox 0.74, but i also play a bit with DOSBox 0.74.3 and DOSBox-X 2022.08.0, and it plays the sound correctly. However, with DOSBox ECE r4479 AppImage doesn't (all in my Linux laptop, btw).
With DOSBox ECE, at the same time as the sound/music, it plays a background beep, with an high pitch. When is no sound there is no beep, it only plays at the same time as the sound/music.
If you don't know, the particularity of the sound/music in this game is one of the few that uses RealSound, that is a way to play PCM Audio Playback on the PC Speaker, which is a bit impressive for what it is, although fast obsolete.
Maybe is only me, although everything else plays fine and i didn't touch the PC Speaker configuration in the conf.
