My tuner doesn't show in the adapters list anymore

Added by Three ByFive about 10 years ago

Hi, I used to have tvheadend running on a different computer, and it worked fine. I moved my tuner card to a new machine (both are running Ubuntu 64 bit), installed tvheadend and I added hts to the video group.

I opened tvheadend through the browser, went to Configuration, DVB Inputs, TV Adapters. The only adapter that shows is 'Samsung S5H1411 QAM/8VSB Frontend'. I don't know what this is, but apparently is was already in my computer.

The card I have installed is a WINTV-HVR-1290. I remember getting this one because it's supposed to work 'out of the box' in linux. Sure enough, lspci -v shows me this:

02:00.0 Multimedia video controller: Conexant Systems, Inc. CX23887/8 PCIe Broadcast Audio and Video Decoder with 3D Comb (rev 04)
    Subsystem: Hauppauge computer works Inc. Device 8551
    Flags: bus master, fast devsel, latency 0, IRQ 34
    Memory at fd800000 (64-bit, non-prefetchable) [size=2M]
    Capabilities: [40] Express Endpoint, MSI 00
    Capabilities: [80] Power Management version 3
    Capabilities: [90] Vital Product Data
    Capabilities: [a0] MSI: Enable- Count=1/1 Maskable- 64bit+
    Kernel driver in use: cx23885

So, I should see this adapter in my list. I am wondering what to try next. Could anyone help me out? Thanks.

I would say that the Samsung frontend is your WinTV adapter - merely identified differently, or a different bit of it is showing up. dmesg/syslog would tell you what's getting initialised at boot time. This is a similar card, and you can see the Samsung chip is the digital demodulator:

Have you tried actually using this adapter? Can you add a network, does it scan?

Has the card registered in /dev/dvb at all? Can you access the card with any other applications?

Does simply restarting tvheadend help at all? I've seen many timing issues where the card hasn't fully initialised before tvh is up and running...

Thanks so much for the reply, you're absolutely right. The Samsung Frontend is a chip on my WinTV tuner card. It did scan. So I'm good with this problem. I'm having some others, but I'll start a different thread about them
