No free tuner is supposed to mean that you cannot change to that channel because you are already recording off of that satellite

For example
If you have Astra in Tuner 1 and Hotbird in Tuner 2
Set the dreambox to record a station on tuner 1 and watch football on tuner 2. When the match was over you went to watch a program on Astra it will give you the "No Free Tuner" error as it cannot change channels or you will lose your recording.

Why it is happening in your case I don't know. I have had that message when I'm flipping through channels very quickly instead of using the Bouquets, but switching away, and then back typically corrects that problem

I figured out my problem

You need to do:

ca_pid_t ca_pid;
ca_pid.pid = c_pid;
ca_pid.index = 0;
ioctl(ca_fd, CA_SET_PID, &ca_pid);

ca_pid_t va_pid;
va_pid.pid = v_pid;
va_pid.index = 0;
ioctl(ca_fd, CA_SET_PID, &va_pid); //Video PID

ca_pid_t aa_pid;
aa_pid.pid = a_pid;
aa_pid.index = 0;
ioctl(ca_fd, CA_SET_PID, &aa_pid); //Audio PID

tmbinc was right, I did need to set the correct PID, I did not know that the c_pid, v_pid and a_pid (all audio pids, if there is more than one stream) all had to SET_PID in the ca device.

Thanks for the reply

Opening the demux on the correct pid should be:

struct dmx_sct_filter_params dmxp;
memset(&dmxp, 0, sizeof(dmxp));
dmxp.pid = e_pid;
dmxp.filter.filter[0] = 0x80;
dmxp.filter.mask[0] = 0xf0;
dmxp.timeout = 1000;
dmxp.flags = DMX_IMMEDIATE_START;
ioctl(fd, DMX_SET_FILTER, dmxp);

Followed by:

ioctl(fd, DMX_START);

If the CA device is used then it needs to have the pid set as well using

ca_pid_t ca_pid;
ca_pid.pid = c_pid;
ca_pid.index = 0;
ioctl(ca_fd, CA_SET_PID, &ca_pid);

If the audio device hasn't been started, how is it possible to start it if enigma2 has /dev/dvb/adapter0/audio0 open and locked. fcntl doesn't work as enigma almost immediately takes control again.

In order for the 7025 to start displaying video/audio it appears (through dmesg) that the ioctl that calls '[AUDIO] enable sync' needs to be sent to xilleon.ko.

However I have been having a few problems:
1. The /dev/dvb/adapter0/audio0 device is opened & locked by enigma2. Using fcntl to change the lock doesn't seem to help as enigma2 reasserts the lock almost immediately.
2. From the enigma2 source, the only ioctl's called on the audio0 device, are:
- AUDIO_STOP
- AUDIO_SELECT_SOURCE
- AUDIO_PLAY
Logically I expected AUDIO_SET_AV_SYNC, but that is never called in the source.

If someone could please help with any of the following it woudl be greatly appreciated:
- What ioctl (if an ioctl is necessary) is called to cause the enable sync?
- Can enigma2 be forced to cause the sync somehow? Through what device?
- If the select source, or set av sync is needed to be called on the audio device, how can that device be opened with the enigma2 lock in place?

I see them now, sorry. I had only seen the F.A.Q. previously.

Yes the Sky card will work in a dreambox, for more information, search sat-industry.net:

Note: I'm in Canada, so I'm unable to test this personally.
