Minecraft Sounds not Starting/Working

Greetings! I have noticed this bug that have been occurring for quite some time and was wondering if you guys knew about it / are able to fix it! So currently when I launch Minecraft on my computer, it works fine and great and all, but when I launch Minecraft when/after I have applications like Discord/TeamSpeak open, the sounds on Minecraft seem to not work - the game is completly silent and is not sending out any source of audio. I can go into my Minecraft settings and see that the Sound Settings are perfectly normal of where I left them but the sounds are still not there. With this bug, I can simply use the debug tool to reload the texture pack "F3+T" and it fixes this issue, but it can get somewhat a little annoying/confusing too for some users who have no idea about fixing this.
