Thanks for your help, Devin -- Devin J. Heitmueller - Kernel Labs http://www.kernellabs.com Hi, I finally give your tree a try with my Dazzle Hybrid Stick on a laptop running Kubuntu 9.10 Karmic (Linux 2.6.31). With the drivers from your tree, the device is properly detected as a Pinnacle Hybrid Pro, but a scan using Kaffeine find DVB-T channels on one or two frequencies only and tuning to one of these channels almost always fail. I reverted back to the drivers from the stock Linux 2.6.31 kernel from Kubuntu 9.10. The scan does not really work better, but using an older list of channels, I can tune channels with significantly less failures.

Even stranger, I received mixed responses from people with the same boards. I haven't had a chance to debug *why* the people who raised problems still had an issue. I continue to believe it's the right fix but I don't know why those people reported problems with it. OK, I will wait then. And other issue raised as well. QAM256 channels are mosaic. I suspect there is some USB speed problems in Empia em28xx driver since demod UNC and BER counters are clean. It is almost 50 Mbit/sec stream... Any idea? I tested modprobe em28xx alt=N without success... What do you mean by mosaic? Can you try using dvbstreamer and see what the overall throughput is? That will tell us if we are not getting the whole stream. You cannot rely on the alt=n for DVB. The max packet size is determined by an em28xx register. I mean picture is bad, very much errors on stream. Look this thread for sample picture: http://linuxtv.fi/viewtopic.php?t=3661postdays=0postorder=ascstart=15 I did some more tests yesterday after sending that mail. Problem seems to be that em28xx does not transfer bytes faster than ~46 Mbit/sec whilst stream is over 50 Mbit/sec. About 5 Mbit/sec is lost... I ensured that comparing towards Anysee E30C Plus DVB-C which has same demodulator (TDA10023). Anysee is just fine, Empia not. I looked stream sizes by using dvbtraffic. Is there any way to speed up Empia to handle streams bigger than ~45 Mbit/sec? regards Antti -- http://palosaari.fi/ -- To unsubscribe from this list: send the line unsubscribe linux-media in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Re: em28xx DVB modeswitching change: call for testers
Hi Devin, I've tested my Empire Dual TV. These are the results: 1) it is recognized as a different card (as you can see from the dmesg 2) it works perfectly in digital mode (even if itdetects less channel than the Dikom DK-300 (aka Kworld 323U?). It scans and tune channels and they can be seen and listened. 3) it can tune analog tv channels 4) it shows analog programs 5) it does not play any sound when showing analog tv programs (I sent the script I use to play sox and the output I obtain execunting it) Xwang Ps I've tried also the Dikom DK-300 but it is recognized as a kworld 323u and digital tv does not work at all (kaffeine does not display the bottom to select it) while the anlog tv can tune channel but has the same audio issue (is the script I use correct?)

Thanks for your help, Devin Hi Devin, excuse my late, but I've done some test. The scanning now work correctly and without problem, all MUX was tuned and channel recognized. With mplayer no problem, for a new channel I must stop the actual channel viewing and start a new one instance of mplayer. I've a problem with kaffeine, and this problem before was not present (I've not tested with the previous temporary patch). To reproduce the problem, is necessary a channel change, and the two channel must be on a different MUX: the first double click on new channel name display an Impossible to tune, if I do a new double click the channel was opened. Is like the adapter was resetted, but not reinitialized on new frequency. Logically the problem not appears if I stop the transmission between the channel change or if I change channel that are located on the same MUX. I hope to have explained well the thing.

I just want to be sure this isn't some sort of issue with conflict between the new and old modules before I debug this any further. Thanks, Devin Hello Devin, I did as you suggested. Unplugged the stick reboot and plug it again. And just to be sure I did it two times. Now the device works, but it is unable to change channel. That is to say, when I use the command vlc channels.conf it tunes to the first station in the channel file and can't change it. Other apps (xine, kaffeine) that seems to change to the latest channel don't work at all. The dmesg output after plugging the driver is in attach. In dmesg I noticed lines like this [drm] TV-14: set mode NTSC 480i 0 I suppose this hasn't anything to do with the analog audio problem, but just to be sure I ask you. Also, using arecord/aplay for analog audio I get an underrun error message arecord -D hw:1,0 -r 32000 -c 2 -f S16_LE | aplay - Recording WAVE 'stdin' : Signed 16 bit Little Endian, Rate 32000 Hz, Stereo Playing WAVE 'stdin' : Signed 16 bit Little Endian, Rate 32000 Hz, Stereo underrun!!!

It is used when you change from analog/digital, when you restore from hibernation and to turn on the demod on hybrid devices, and to turn it off after stopping DVB. If you're having troubles there, then probably the DVB demod poweron/reset gpio sequence is wrong or incomplete.

If you're having troubles there, then probably the DVB demod poweron/reset gpio sequence is wrong or incomplete. The em28xx_dvb_bus_ctrl() callback should already be putting it into digital mode when the frontend gets opened. The point behind the change is that we should not be switching in and out of dvb mode whenever somebody starts/stops streaming. It should be controlled based on opening closing the frontend (which is what the ts_bus_ctrl callback should accomplish). We ran into the issue because the dvb gpio for the board in question actually strobes the reset rather than just taking it out of reset. While I could change the dvb_gpio to match some of the other boards, we really *should* be strobing the reset after powering up the chip. If we're really relying on the calls in the start_feed() callback when coming out of hibernation, then the code is broken in that case as well, since there is no guarantee the demod is properly re-initialized.

em28xx DVB modeswitching change: call for testers
Hello all, I have setup a tree that removes the mode switching code when starting/stopping streaming. If you have one of the em28xx dvb devices mentioned in the previous thread and volunteered to test, please try out the following tree: http://kernellabs.com/hg/~dheitmueller/em28xx-modeswitch In particular, this should work for those of you who reported problems with zl10353 based devices like the Pinnacle 320e (or Dazzle) and were using that one line change I sent this week. It should also work with Antti's Reddo board without needing his patch to move the demod reset into the tuner_gpio. This also brings us one more step forward to setting up the locking properly so that applications cannot simultaneously open the analog and dvb side of the device.
