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

Hi, Is my problem with saa7134 and FM radio related to this
mailing-list? If not, can someone point me to correct mailing-list?
I have two LifeView FlyDVB-T trio PCI cards, and I have some serious
problems with FM radio tuner.
I am using kernel 2.6.21.3 SMP, but same problem is with kernel 2.6.20.X
and even with latest CVS tree from linux.tv (17.6.2007)
Sometimes (very often) one or both cards are just frozen, I can't tune
radio (hear nothing).
After restart, situation sometimes change.
From log:
+ I am getting many dsp acces error on problematic card:
saa7133[0]: dsp access error
saa7133[0]: dsp access error
saa7133[0]: dsp access error
saa7133[0]: dsp access error
saa7133[0]: dsp access error
saa7133[0]: dsp access error
saa7133[0]: dsp access error
+ Problem is related to this message from dmesg
aa7133[0]/audio: tvaudio thread status: 0x100000 [no standard detected]
If you are developer I can give you full ssh access to this station.
Has someone similar issue, is there any working solution?
I am sending dmes log as attachment...
