I have tried playing 8 consecutive matches in Dota 2 using ta, but I couldn't find the issues you mentioned. If you're willing, you can assist me further with the following steps. Firstly, you need to add "-console" to the launch options of Dota 2. Then, launch Dota 2 and enter the game. Press "\" to open the console and type "soundinfo" then press Enter. This will display all the currently playing sounds. Once you're ready, when you hear the hissing sound, press "\" again to open the console, type "soundinfo" and press Enter. Then, right-click and copy the playing sounds and provide them to me. I will promptly work on fixing the issues you mentioned.
