I am running TLD on an Ubuntu 18.04.1 LTS desktop PC with on-board sound, but occasionally also booting into Windows 10 on the same PC. A dual-speaker setup is used. Under Ubuntu, sounds from e.g. waterfalls appear loud and with proper stereo volume effect when the source is at the front or left/right. But when turning away from the source, the sound disappears almost completely. Under Windows, the directional effect is far less pronounced and feels more realistic.
Im am curious if other Linux users experience a similar affect, or could this could be due so some improper setup on my PC? The sound setup in Ubuntu appears very basic, without any settings to change stereo/surround effects.
I too have noticed this. I've been especially noticing it lately as my guy's been living at the stone church in DP; the supercardioid effect of the SFX is completely noticeable with the waterfall just around the corner from there.
