Changing delivery system from DVB-T to DVB-T2

[enchesss]

I will try above advice asap.

In meantime - I seem to be able to trick myth into scanning

I needed to put another tuner card in 'Winfast' barnd - not sure model.

I left Quad in and swapped aerial to winfast -

Changed tuner card setting from adapter0 to adapter 4

tried to scan using adapter 4 but no channels trying input connections scan.

I then changed aerial back to quad hd and changed the tuner card back to adapter 0

did another scan and got all channels ok

what can possibly go wrong now

IMO should have worked straight out of the box.

Sounds like another quality Belling Lee (VHF) connector/ patchlead...
Really wish Hauppauge would just use F connectors on all products.

It did work out of the box - using Kaffeine

The cards do not even need to be set to DVB-T1 - even though I think there is no DVB-T2 in Sydney - it still works now - evern if cards are left to default DVB-T2 setting.

Have to cross fingers doing a reboot or upgrade though.

2 days ago - as a result of having cards working - the:

var/log files:

syslog and kernlog became extreemly large - e.g. 80Gb and they used all disk space.

There were a lot of cx28 logs

I turned off logging on grub boot options and is now ok



FYI

An attempted fix was to tun off the option "open on demand" in add tuner card settings - this resulted in the tuner cards not working on boot

That option has been reset to default 'on' and all is working with no large syslog or kernlog files atm

[enchesss]

further testing results in tuner card not working if the line:

GRUB_CMDLINE_LINUX_DEFAULT="cx23885.debug=8"

is removed from grub

however

if the line is included in grub the log files increase at about 1mB per second resulting in extremely large usage up to 40Gb per hour

[enchesss]

ok - so

removing :

v4l-cx23885-avcore-01.fw

from /lib/firmware has

NOT worked.

All tuner cards working - however there are:

very large log (syslog and kern.log) files being generated


I can still tune using all four tuners however

even with one tuner - I am getting large syslog and kern.log files as reported here:

https://github.com/b-rad-NDi/Ubuntu-med ... /issues/19

and

https://github.com/b-rad-NDi/Ubuntu-med ... /issues/41

Maybe I have the wrong (old) firmware??


Am trying to prevent syslog writing - however - it is not really an answer to the real problem and probably wont solve the large kern.log files either

[enchesss]

further testing results in a timeout for channels if the line:

GRUB_CMDLINE_LINUX_DEFAULT="cx23885.debug=8"

is changed to any number less than 5

Using

GRUB_CMDLINE_LINUX_DEFAULT="cx23885.debug=5"

Results in working tuner cards - and smaller syslog and kern.log files

But they are still increasing at a fast rate - about 1 Mb per 10 seconds

The debug settings could just be changing the timing or serializing of some operations by loading the filesystem.

Do you have a large enough signal & tuning delays (see MikeB2013's post) ?
Does Kaffeine have configurable tuner delays?

I successfully used "Open on Demand " for only one of the (4) tuners.
If you have to use "Open On Demand" to get the card/tuners to show up suggests mythbackend is started before the tuners are initialized.
That's hard to believe unless the tuner is a network device.

If you stop & re-start MBE do the tuners always appear ("Open On Demand" disabled)?
