Help Request: DM1105 STV0299 DVB-S PCI - Unable to tune

[Shaun Murdoch <scrauny@xxxxxxxxx>]

Hi everyone,

First post so please be gentle :-)

I was wondering if anyone can help me please - I am trying to get a DVB-S PCI card working with Linux (Ubuntu 9.04). So far I can get the card recognised by Linux, but it won't tune - Kaffeine does tell me that there is 95% signal and 80% SNR, and I am using the same frequencies etc that a standard Sky box uses.

The card is very common on eBay so I am sure there are plenty people who have tried this / would want this working.

Some details that I hope will help someone who knows more than I do about this!

The card is one of these:

lspci:

03:09.0 Ethernet controller: Device 195d:1105 (rev 10)

My dmesg output - looks ok?:

$ dmesg | grep DVB

My output from scan - the problem:

This is the correct satellite for my location (south UK), I believe. Have tried plenty. Nothing locks.

I'm using the latest liplianin drivers - did a mercurial checkout and build today:

$ modinfo dm1105

Have also tried the latest v4l-dvb drivers and get exactly the same tuning problems.

Finally, dvbtune appears to say I have signal but cannot lock:

$ sudo dvbtune -f 1177800 -s 27500 -p v -m -tone 1 -vvvvvvvvvvv

So I am thinking that this could be a driver issue? If the card has good signal and SNR in Kaffeine, and dvbtune says it has signal and carrier - but cannot lock?

Please can someone help me debug this?

Thanks a lot!

Shaun
