My Twitch is extremely quiet even though everything is at full volume?

Hey is already at the top of the question. I use the TwitchWindowsApp and somehow the streams have been very quiet for a few days although I have everything at full volume. Do you have any suggestions on how I can make them louder?

Do you hear through headphones or PC / laptop speakers?

Any sound drivers updated?

For me the problem was that my rear headset connection on the PC was suddenly quieter, so I simply used the front one.

Yes, listen over PC speakers that is generally only in the Twitch app
