Hello, at first let me appologize for my poor english.
I searched similar problem here but not successfully.
When I bought SL510 2 years ago everything was OK.
The connection worked correctly but than (I think) some drivers were updated and sound from HDMI connection get lost.
I noticed in my LENOVO THINKVANTAGE TOOLBOX in System History in DEVICE TESTS that INTEL(R) High Definition Audio HDMI - failed at 24.7.2010.
There is notice: http://dodo-kolin.rajce.idnes.cz/problem#Novy_obrazek_4_.jpg
When I run this test now, the test passes but sound from TV does not work.
There are detailed device informations for:
