Hi,

I can confirm the same issue, although I was only playing radio from DVB
streams so no SDR involved. Reverting the kernel back to a previous
version with "rpi-update a91c44b2f022646424a55171151b6a64ed243642"
solved it, but I never got around to determining what the actual problem
was. There's a git repo (somewhere, I don't remember the URL) that
contains the history.

rpi-update will only update the kernel (and maybe firmware?) but not the
OS, so I'm sure there's nothing broken in the tools and libraries.
