Live tv black screen, no audio from RTL2832u dongle

[Kwekkel]

Hello,

I'm a newbee with NPVR. I'm trying to get live tv up and running but no go so far.
This is my setup:
Windows 8.1 pro, firewall disabled.
USB dongle RTL2832u, drivers auto installed by Windows when plugging in the dongle.
Installed the SAF codec pack.

-chanannel search ok
-tried several codec settings

I noticed that the file in c:/temp stays at 0 bytes. So it looks like that there is no information coming from the dongle.

Thanks in advance for any advice.

Your best is probably to reproduce the problem, then zip and attach the c:\users\public\npvr\logs directory.

Thanks.

I've been reading many posts on this forum and this question was asked several times. How could I not think of this myself. :o
Sorry... I'll capture the log first.

Please find attached my logs.
Hope it helps.

The logs look like the device isn't locking onto a signal:

2014-07-22 21:23:08.835 [DEBUG][14] locked=0, present=0, strength=0, quality=0 (took 0ms to check)

If you do a recording, to you end up with a file with data in it, or zero bytes long?

Hi,

Both the file in C:\TEMP for live TV and the file for recordings are zero bytes.

Assuming you've got a good signal, then unfortunately it's sounding like buggy drivers for this device. Maybe see if you can find a different version of the drivers that behaves better.

The signal should be ok. If I plug the coax directly into my TV it's working fine. The dongle itself should also be fine because it worked perfect for Software Defined Radio.
Looked at the drivers: the one installed is from 2009. When I search for an updated driver it says no newer drivers found.
When I remove the driver and let Windows search for new hardware, a 2014 version driver is installed.
Then after this, still black screen. Ad after rebboting the PC the driver has reverted back to the 2009 version.

Really confused here.

does it work with the software that came with it?

I have a spare RTL tuner also bought for an SDR application but was sure I had it working with NextPVR. On my server I replaced one of my USB tuners with the RTL tuner but even after a reboot failed to work giving zero byte recordings and failing to lock.

However I dug out my old server running NextPVR 3.1, deleted all devices and channels, installed RTL tuner, did a rescan, updated EPG and was able to watch live TV. The tuner is using a 2009 driver running on Vista.

So the tuner will work with NextPVR but I don't know why it wont work on my current server. I just noticed that you said that you were able to search for channels which must mean that the tuner is working.
