Re: [PATCH] em28xx: fix for Dikom DK300 hybrid USB tuner (aka Kworld VS-DVB-T 323UR ) (digital mode)

["Andrea.Amorosi76@gmail.com" <Andrea.Amorosi76@gmail.com>]

Continuing the testing for the analog part of the device, I've 
discovered that the main kernel driver (the one without the proposed 
patch)  works better,  even if not perfectly, as far as analog tv is 
concerned.
In detail analog sound is present but is very low and noisy  (it seems 
to be listening to a very  distant radio station).
So there is something in the patch that breaks the analog tv sound 
(which however is not very usable in the main driver being so noisy).
Which one of the modified setting can interfer with the analog tv sound?
Thank you,
Andrea
