[linux-dvb] Kworld DVB-T 323UR problems

[linux-dvb] Kworld DVB-T 323UR problems

[Laszlo Kustan]

Hi everyone,
I have a Kword DVB-T 323UR connected to a Linux Mint 7 Gloria (based
on Ubuntu Jaunty), kernel 2.6.28.
I successfully compiled em28xx, the firmware was obtained based on these steps:
1) Download the windows driver with something like:
wget http://www.steventoth.net/linux/xc5000/HVR-12x0-14x0-17x0_1_25_25271_WHQL.zip
2) Extract the file hcw85bda.sys from the zip into the current dir:
unzip -j HVR-12x0-14x0-17x0_1_25_25271_WHQL.zip Driver85/hcw85bda.sys
3) run the script:
./extract_xc3028.pl
4) copy the generated file:
cp xc3028-v27.fw /lib/firmware

My windows driver is called embda.sys, so I'm not sure whether the
firmware is 100% good for my tuner or not.
I have a couple of problems:
1. no analog audio, but I found out this works with workarounds

I tried several tricks:
a. sox -c 2 -r 32000 -t ossdsp /dev/dsp1 -t ossdsp /dev/dsp
this works, but with a 4-5 second delay between audio and video

b. arecord -D hw:1,0 -r 32000 -c 2 -f S16_LE | play -q -c 2 -r 32000 -t wav - &
I get an error:
laco@laco-desktop ~ $ arecord -D hw:1,0 -r 32000 -c 2 -f S16_LE | play
-q -c 2 -r 32000 -t wav - &

         please, try the plug plugin
arecord: pcm_read:1529: read error: Input/output error
play wav: Premature EOF on .wav input file

c. install modified tvtime from mcentral.de
I get an error in this case too:

My arecord -l output is:

2. my remote is not recognized. Here is the em28xx part from dmesg:

[11241.922736] em28xx-audio: device is currently in analog TV mode

Nothing about input devices here and neither in /proc/bus/input/devices.

3. heat problems
I noticed that when it is connected, it gets quite hot, even if no dvb
software is running. In Windows it does not get so hot, even when
watching tv.

Sorry for this long mail.
The first point would be the most important to solve, if you need more
details to help me, no problem.
Thanks, Laszlo

Hello Laszlo,

Please send correspondence to the linux-media mailing list, as the
linux-dvb list is deprecated.

Your firmware is fine.  The extract_xc3027.pl script will *only* work
if the md5 checksum matches, so if it matched then you ended up with
the correct firmware.

Regarding #1, the audio is working correctly.  The problem is that for
raw capture devices there is no way currently for the v4l2 to inform
applications where to find the ALSA device that provides the audio.
Your card is behaving consistently with *every* other product
currently supported that provides a raw video stream (as opposed to
products with an MPEG encoder onboard).

The reason you see the audio being out of sync with the video is
because of buffering of the audio prior to playback.  You can usually
control this behavior with command line arguments for arecord or sox.

Regarding #2, if your remote does not work, then the driver probably
does not have a remote control profile defined for your product.  I
really should write some sort of script to make it easier to define
these.  If that is something you want to work with me on, email me
off-list and I will go through the steps with you to get a profile
into the kernel for your remote.

Regarding #3, it is true that all of these devices run hot by design.
I've done considerable analysis into the issue, and it turns up that
the devices run at the exact same temperature under Windows as they do
under Linux when capturing.  However, the Linux driver does not
properly shut down the tuner when not in use, which effectively means
the device is running at that temperature all the time.  This causes
people to believe the device runs hotter under Linux, when in fact
they are just noticing that the device is always running hot.  Mauro
did some work in this area to improve the driver, and I really should
follow through and complete that work.  Again, this behavior occurs
with almost all em28xx devices that use xc3028.

please pay attention to that line... it probably will not work with usb 1.0.

Hi Markus,
Sorry, it seems that sometimes my usb is not recognized as 2.0, I wonder why
this happens.
Anyway, I'll send you in the afternoon a correct dmesg output, but the
results are the same: same problems with analog routing and no remote.
After I installed your tvtime version (had to install the deb version as the
sources are not available on your site (internal server error)), there were
some problems with libswscale (the link had other name than tvtime was
looking for), I renamed the link and that's how I ended up with the error
message I already wrote:
Access type not available

Any idea how to get rid of this or any feasible solution for the analog
audio?

Thanks, Laszlo
