The AVerMedia A771 is a, so called, budget or software decoding PCI DVB-T card. These cards work well with the latest kernels.

It is the successor to the original AVerTV DVB-T card, the A761 model.


The AVerMedia A771 features:

  • a MT352 demodulator ... The first few versions of the MT352 driver didn't work so well, so try upgrading if you have problems with tuning.

Kernel configuration

If building your own kernel, you would want to select all options under "I2C" and all options under "Video for Linux" (incl. "DVB", obviously).

AVerMedia actually wrote a nice HOWTO for Setting up an AVerMedia A771 DVB-T card under Linux ... likely very dated by now, but worth a look. AVerMedia's guide is nolonger on their site, but it can be found on Archive.org

After compilation, to get the card to work simply call "modprobe dvb_bt8xx". Then run, "scan" (from dvb apps) or MythTV as normal.
