[dvblast-devel] Fwd: Some trouble with choose right frequency on Hotbird

[Kompan Kolia]

I fix this problem.

Problem with setting uop dvb-tone with diseqc miniA miniB

When i use Diseqc MiniA or miniB (may be 1-4 too) dvblast don`t set FE_SET_TONE

And why you do
    /* Switch off continuous tone. */
    if ( ioctl( i_frontend, FE_SET_TONE, SEC_TONE_OFF ) < 0 )
    {
        msg_Err( NULL, "FE_SET_TONE failed (%s)", strerror(errno) );
        exit(1);
    }
    msleep(100000);
???
