"frequency 0 out of range" shown in syslog when starting TVH - also shown when doing dmesg | grep -i dvb

Everytime I start TVH I see the following error message for the adapters:

Tuning in XBMC and TVH works fine though and it works perfectly fine to watch LiveTV via XBMC.

Note also that the tuning errors only is happening for adapter 0 to 5 out of my 8 adapters.

Sorry to keep chatting in this thread that was changed from "New" to "Invalid".

I still believe it is TVH doing something strange during the startup sequence that causes these "adapter 2 frontend 0 frequency 0 out of range (950000..2150000)" messages from kernel in the syslog:

Oct 5 23:16:30 tvserver tvheadend17114: dvr: Creating new configuration ''

I downloaded dvb-apps. I shutdown TVH and did a SCAN according to the info at http://www.linuxtv.org/wiki/index.php/Scan to create a complete channel list for the satellite THOR 1.0W (actually it is 0.8W).
After that I tuned each adapter to a channel using Szap-S2 app (http://www.linuxtv.org/wiki/index.php/Szap-s2and). Then I started TVH again and voilaaaa! No more messages in the syslog about "frequency 0 out of range"! :-)

So it definately looks like that when TVH starts it initiates the adapters without having a valid frequency set?

Yes, there's an early DTV_TUNE request without any parameters set, which is explained here: http://tvheadend.org/projects/tvheadend/repository/revisions/85376b622c5a7354240ae43068ca5aa6b293bcb9

Just ignore this. It's harmless.

hello
I have Tvheadend 4.1-999~gee9b6da with 2x TBS 6985 DVBS/S2 (8 tuners total) fresh installation and still continue to have DVB: adapter 7 frontend 0 symbol rate 0 out of range (1000000..45000000) and in the Tvheadend have the error linuxdvb: TurboSight TBS 6985 DVBS/S2 frontend : DVB-S #0 - failed to tune [e=Invalid argument]
anyone already fix that or have a idea to fix?
i try to use hispasat 30W and have good signal.

It's not broken. The driver just doesn't like the values passed to it from Tvheadend. If you're manually adding muxes avoid using AUTO & see if it goes away.
