Hi,
I have the XPS13 (9343) laptop for almost a year now.
In the last week i'm suffering a weird issue, in which my speakers suddenly like "change their quality" to a very low one. Whatever sound I play (windows chimes / youtube music) - the sound is distorted and metallic. The even stranger thing is, that the problem consists also when I plug in headphones, so it should be a software issue I suppose.
After restart, the problem is solved, until the next time.
I have latest Realtek drivers and ran the Dell Support checkup few times.
Thanks in advance!
