Simon Long představil na blogu Raspberry Pi novou verzi 2017-06-21 linuxové distribuce Raspbian určené především pro jednodeskové miniaturní počítače Raspberry Pi. Společně s Raspbianem byl aktualizován také instalační nástroj NOOBS (New Out Of the Box Software). Z novinek lze zdůraznit IDE Thonny pro vývoj v programovacím jazyce Python a především offline verzi Scratche 2.0. Ten bylo dosud možné používat pouze online. Offline bylo možné používat pouze Scratch ve verzi 1.4. Z nového Scratchu lze ovládat také GPIO piny. Scratch 2.0 vyžaduje Flash.

    Bylo by fajn, kdybys sem to to řešení postl, když víš, že to štve tolik lidí... :-(

    Řešení podle https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.15/+bug/29789/comments/40:
     I solved a problem passing i2c_udelay parameter for bttv module. Now my /etc/modprobe.conf looks like this:
      options bttv radio=1 tuner=28 card=72 gbuffers=4 i2c_udelay=128
      Perhaps i2c_udelay=16 will be enough too - need to check. With this parameter sound from tv works ok on 2.6.22 (from Gutsy) as well as on 2.6.24rc5 (from Hardy Alpha2).
    Hurá! Jede to.
