This patch solved problems with muted radio on Lifeview FlyTV Trio. So
can anyone commit it to git? It is based on latest patch from mrec
repository http://mcentral.de/hg/~mrec/v4l-dvb-experimental/summary

I would like to offer TV Tuner Lifeview FlyTV Trio (DVB-T, DVB-S, Analog
TV, Analog FM) anyone who can solve BUG in saa7134 radio support.
I am using those tuners in one project for streaming DVB-T and analog FM
together. If I am streaming only DVB-T everything works without
problems, but when I try to stream FM radio strange things happens.
In dmesg it is "dsp access error", but there are other issues, like no
sound from some cards (there are 3 cards in one PC), on every cold boot
it differs (for example: first boot - radio tuner 1 works, second boot -
radio tuner 3 works). I think the main problem is related to this issue:
http://lists.zerezo.com/video4linux/msg17820.html
I am using actual git tree from linuxtv.org
I can give you root ssh access to the PC, or If you are from Czech
Republic I can borrow you one card.
For my project I tried those cards:
* Lifeview FlyDVB Trio - with problem above
* Pinnacle PCTV Hybrid PRO PCI 310i - same problem like FlyDVB Trio
* Leadtek WinFast DTV2000 H - there are some issues with DVB-T and
radio is not supported yet
* Hauppauge WinTV HVR1300 - radio is not supported yet
If you know about other TV hybrid tuner with working DVB-T and FM radio
at the same time, please send me model name.
