Re: audio renderer error
Same problem. New Xps13.
After several long sessions with Dell's attempts to fix, they finally told us to send it back. We did. They returned it to us with a new operating system, drivers, etc. Worked fine. For a couple of weeks. Now back to the same old.
This is our second xps13. The first one, now about three years old, works like a dream --- which is why we bought this one.
Time for a refund?
