Installing and setting AVerTV Digi Volar X in Debian

AVerMedia AVerTV DVB-T Volar X (A815) is an Avermedia usb device capable to capture and show DVB-T TV signals.
This device is able to also show HDTV DVB-T signals.

http://linuxtv.org/wiki/index.php/Afatech_AF9015


LINUX KERNEL DRIVER

The device contains an Afatech AF9015 Chip.
Supported in kernel since version 2.6.28.

NOTE: If you have an older kernel version you will have to compile the kernel module:
Compile AF9015 module tutorial.
AF9015 Kernel Module Source.


IMPORTANT: Although AF9015 module is already available in the kernel, it NEEDS ADDITIONAL FIRMWARE INSTALLED to work.


DETECTING THE DEVICE

I plug the usb device:

$ lsusb
... ID 07ca:a815 AVerMedia Technologies, Inc. AVerTV DVB-T Volar X (A815)


Kernel log shows:
$ dmesg

dvb_usb_af9015: probe of 2-1.2.1:1.0 failed with error -2
usbcore: registered new interface driver dvb_usb_af9015


We observe it detects the usb device. It also tries to initialize the IR remote, but in the end it does not find a suitable firmware.


INSTALLING FIRMWARE

We need the file: dvb-usb-af9015.fw

Available from this URL:
http://www.otit.fi/~crope/v4l-dvb/af9015/af9015_firmware_cutter/firmware_files/

Right now (2012-02-25) this firmware file is still not available in non-free section of Debian:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=534379

We download the firmware file:
$ wget http://www.otit.fi/~crope/v4l-dvb/af9015/af9015_firmware_cutter/firmware_files/4.95.0/dvb-usb-af9015.fw

Copy firmware into /lib/firmware:
$ sudo cp dvb-usb-af9015.fw /lib/firmware/


CHECKING IF FIRMWARE WAS SUCCESSFULLY INSTALLED

Unplug and plug again the device.
Let's check if firmware was successfully installed:

$ dmesg

it says "dvb-usb: found a 'AVerMedia AVerTV DVB-T Volar X' in warm state" so it looks OK.

INSTALLING DVB-APPS

Once DVB driver works OK we need to install some useful DVB related tools and configuration files:

$ sudo aptitude install dvb-apps


TESTING OUR DVB DEVICE

We have already installed the driver and some tools, now we are going to test our DVB device:
http://linuxtv.org/wiki/index.php/Testing_your_DVB_device

First using scan tool we are going to create a channels.conf file suitable for other apps like mplayer or me-tv.
http://linuxtv.org/wiki/index.php/Scan

You will need an initial configuration file for your DVB-X system and geographical location.
E.g: mine is DVB-T for Spain and Huesca,

Check files in dvb-apps package:
$ dpkg -L dvb-apps

Initial config file for DVB-T Spain and Huesca is:
/usr/share/dvb/dvb-t/es-Huesca

NOTE: If you do not find any suitable initial scan file, you could use w_scan tool

Now we create a channels.conf file:
$ scan /usr/share/dvb/dvb-t/es-Huesca > channels.conf

Other scanning tools:
Comparison_of_DVB_frequency_scanning_commandline_utilities


TUNNING A CHANNEL AND DISPLAYING IT

We tune a channel using Zap tool
http://linuxtv.org/wiki/index.php/Zap

E.g: using just generated channels.conf file we select "ARAGON TV" TV channel:
$ tzap -r -c channels.conf "ARAGON TV"
Without ending this command with Ctr-C we launch mplayer in another console:
$ mplayer /dev/dvb/adapter0/dvr0 -framedrop -fs

And then you should see the channel you just selected.


WATCHING DVB-T USING MPLAYER

We are going to watch DVB channels using mplayer only (not using tzap tool to tune it)

Copy channels.conf file to mplayer configuration directory:
$ cp channels.conf $HOME/.mplayer/

Now if we want to watch "ARAGON TV" channel:
$ mplayer dvb://"ARAGON TV" -framedrop -fs

Some keys allow us to switch TV channels when running mplayer.
'h': next channel
'k': previous channel


CAPTURE TO HARD DISK

We tune the channel we want to capture
$ tzap -r -c channels.conf "ARAGON TV"

Then we simply perform a cat from dvr0 device file to the file we want to save the stream to.
$ cat /dev/dvb/adapter0/dvr0 > capture_file

To watch again the captured stream:
$ mplayer -framedrop -fs capture_file

NOTE: We could use dvbstream tool instead of cat.


W_SCAN TOOL

w_scan tool allow us to generate an initial scan file.

Download and build W_scan
http://wirbel.htpc-forum.de/w_scan/index_en.html

$ wget wirbel.htpc-forum.de/w_scan/w_scan-20120128.tar.bz2
$ tar xvjf w_scan-20120128.tar.bz2
$ cd w_scan-20120128/
$ aptitude install linux-libc-dev # it needs this dependency.
$ ./configure
$ make


We create the initial scan file. I have to pass -c ES argument for Spain:
$ w_scan-20120128/w_scan -ft -c ES -x >> initial_scan_info
$ scan initial_scan_info > channels.conf # generate channels.conf file.


ME-TV

There are several interesting programs suitable to watch DVB TV and radio streams:
http://linuxtv.org/wiki/index.php/TV_Related_Software

http://linuxtv.org/wiki/index.php/Me_TV
Me-TV is able to scan channels, show TV program information, record streams, network broadcast, etc.

$ sudo aptitude install me-tv
$ me-tv

Thank you very much for this guide! As a linux newbie I was trying to set up my AverTV Volar for hours; with no hope.

With your help, I could make it work within minutes. Fantastic! :-)

Glad it was useful to you!

It doesn't work in Sparky Linux, my dmesg command doesn't display any "IR" Line, and my "make" and "make install" efforts are useless.
Does anyone knows how to make it work in Sparky? I'm sick tired about drivers, the .diff file, unavailable tools / packages...
