Hello i have the problem that no video streams are working anymore.
Iam Using Firefox and also testet Brave. On my Handy all Streams are working fine with the same WLAN connectet.
I testet disabling adblocker and hardware acceleration on firefox but no luck.
Youtube and other streaming sites are buffering but the videos dont start.
My CachyOS is up to date and and all apps also…
Youtube says that i should restart my PC if the Video dont start in an moment.
I also restartet my router…
Maybe you can help me. 
Update: Seems to be a Sound Driver Problem…
Try to fix it…
