Some weird FS sound issues

[HeathcliffMontague]

First, I don't hear any engine sound when driving. Bike, car, whatever. I hear it quite loudly when idle and zooming in next to the bike, but once I start driving I hear nothing.

Second, no sound when TP-ing, even if the sound is enabled. No biggie, just a bit weird. Media seems to work just fine, music works fine when enabled. 

On my laptop and on Wifi for the time being, handles OK enough. Could be my laptop settings, but I only get two options: Speakers Realtek Audio or Headset (when connected). Everything works normally in the LL viewer.

Suggestions appreciated, specs below.

I experience the same from time to time, I do not think, it is your laptop - as I also get this lack of driving sounds on my laptop and stationary gaming PC.

Have you tried to clear the sound cache?
