Hi all!
Since I didn't find any ticket or forum entry here: I've recently found out that timeshift on radio channels seems to be not working as expected. I am on 4.2.8-dmo1 on Debian's Buster.
I would expect that it works like on a tv channel but actually it allows me to pause but neither back/forward seeking nor going back to live are possible.
Is this a known issue or maybe am I missing some hidden config option?
Regards,
Richard
