No HDMI audio repetitive problem

Hi, 

I have a HP Pavilion DV6 1308sl and my problem HDMI audio is here for the 3rd time.

The first time I get it solved by finding some drivers on another site. Next time I went on Device manager and let both the AMD High Def. Audio Device and the IDT High Def Audio CODEC update by themself (right click on the device and selecting "update").

The 3rd time (a couple of weeks after the 2nd) I've tried the same, but I've been told by the system that they are already as updated as possible. The day after (today) I tried the same and this time the system succeeded in updating the AMD HD Audio Device and it seems that this time the result is successfull.

Please, tell me one thing. I think that this was not the last time of that kind of problem and the next time it happens, can I try the procedure of downloading these 2 files you've suggested in this problem solving of ‎04-22-2011, Message 4 of 67:

...or there is something more updated/other solutions?
