Hi Torbjörn,
Try commenting out this line in si2168.c and let me know if that changes things.
if (c->delivery_system == SYS_DVBT2) {
/* select PLP */
cmd.args[0] = 0x52;
cmd.args[1] = c->stream_id & 0xff;
// cmd.args[2] = c->stream_id == NO_STREAM_ID_FILTER ? 0 : 1;
cmd.wlen = 3;
cmd.rlen = 1;
ret = si2168_cmd_execute(s, &cmd);
if (ret)
goto err;
}
Cheers,
-olli
