Subject: A16D (XC3028) FM radio regression -- constant 2.75Mhz offset
Date: Mon, 18 Oct 2010 17:07:27 +0000 (UTC)	[thread overview]
Message-ID: <i9husf$77l$1@dough.gmane.org> (raw)

Hello,

Since upgrading to a 2.6.35 kernel I've found out that all FM radio 
stations have been offset by 2.75Mhz . Card is AVERMEDIA A16D, using 
XC3028 tuner (firmware v27). 

I've bisected the issue to commit:
7f2199c03b4946f1b79514b3411e3dbf130a6bba
V4L/DVB: tuner-xc2028: fix tuning logic to solve a regression in Australia

Seems that the code is not properly handling anything other than 
T_ANALOG_TV, T_DIGITAL_TV. Thus, when new_mode is T_RADIO, it blindly 
offsets freq by 2.75Mhz assuming it's DTV8 or DTV78. I'm worried why 
nobody has complained yet about this, though.

Javier.
