LibreELEC (Krypton) v8.1.0 BETA breaks my Hauppauge 1191 WinTV-HVR-955Q USB TV Tuner

1st Official Post

    Did the V8.1.0 update and the tuner stoped working. Only 1 tuner showed up in tvheadend. Channel scanning in tvheadend returns nothing. Did this twice, once via upgrade, once via clean install. Had to do a clean install of v8.0.2 to get it back.

    I have the same problem with the WinTV-HVR-955Q ATSC tuner after I upgraded to the latest beta also. The tv adapters just never show up in the tvheadend settings. Going back to libreELEC 8 fixes the problem.

    This still seems to be broken (I'm also using the 955Q). Is it possibly related to this revert? This tuner did always list two adapters in TVHeadend. This is a real bummer, I think that particular tuner was one of the cheapest supported tuners.

    Here's another dmesg log with a stack trace from TVHeadend trying to use the dvb driver, looks like:

    I can confirm I'm having the same issue with the Xbox One variant of the adapter connected to a Pi2 or Pi3 (tried them both). Rolling back to 8.0.2 fixes the problem.
