[PATCH] saa7134 - ir remote for sinovideo 1300

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Have a tv tuner believe to be sinovideo 1300, and the remote has h-338 in the back, the tuner is detected as saa7134 proteus 2309, and working fine, the patch is for the remote.

following buttons supposed to be working: all the number button, channel up and down, volumn up and down, off, mute, full screen, recall, snapshot, tv.  Some buttons do not have valid entry for tvtime, so I did not map them(record, stop ...)

to apply, use command
modprobe saa7134 card=157
if it does not work, use
modprobe saa7134 card=157 ir_debug=1
and send me(yahoo.com) the output of dmesg(after modprobe and after a button is pressed)
