The audio in TS 64-bit has recently gone very low for me, though 32-bit seems to be unaffected. Both the in-game and system volumes have been maxed out, volume mixer has my default speakers set and maxed, and I've run the Setup_Audio batch and done a complete reinstall, all to no avail. Other games on my PC run at normal volume, so I've no idea where to turn now. I have submitted a support ticket, but wondered if anyone here had any ideas as well.
