Hermann,

Thank you for your response.
The card is a M115S not M1155 as first reported. I mis-read it when looking at it in the Vista Device Manager. It would seem theirefore that it is a M115 derivative. I'm not sure what the 'S' would stand for - Sony perhaps? You are right that it is shipped with a Sony Vaio machine, in this case a Vaio VGX-TP1E Media Centre PC. 

I've played around with the saa7134-core module and added the definition for the card in question (i.e. I copied the definition for M1155 using 1461:e836 - as indicated by dmesg - rather than 1461:a836 as for the original M115). Obviously I don't just expect this to work. However dmesg now reports:

[   38.915676] saa7133[0]/dvb Huh? unknown DVB card?
[   38.915676] saa7133[0]/dvb frontend initialisation failed

So maybe its now down to identifying the tuner. The only information I could get about the tuner was that it has both a 'BDA Analogue Tuner' and a 'BDA Tuner' the latter of which is presumably the DVB tuner. Sorry but don't know what the BDA part stands for and I can'r see it listed in the supported tuner devices. Any idea if such a tuner - even if only analogue for now - is supported?

John.

the etc can hold some information, better don't drop parts of the eeprom
dump.

The card is not yet supported, but was seen previously on some Sony Vaio
stuff.

We have no reports for any details on it, but there is a slight chance
that it is very similar to card=138, the AVERMEDIA_M115.

There is no DVB-T support yet and you would need recent XCeive firmware
in /lib/firmware if my guessing is right.

Are you sure DVB-T for this one is announced at all?

Cheers,
Hermann
