Users / SOLUTION: TT1500 (budget_ci) conflicted with snd_aw2 driver
« on: June 29, 2008, 12:59:20 am »

anyone having problems with a Technotrend 1500 PCI card? Perhaps here is the solution:

I finally don´t believe that a plain LMCE installation will work with any PCI card that contains a phillips saa7146 chip for controlling the frontend (tuner).

The linux kernel in LMCE 7.10 contains a driver "snd_aw2" for an audiowerk sound card. This driver has a bug, so it is loaded for every saa7146 chip probably in any PCI device (?). For me, it was loaded instead of the correct frontend driver for my TT1500 DVB-S card. After blacklisting the driver in /etc/modprobe.d, the DVB card finally works! HEUREKA!

Just add a line

blacklist snd_aw2

to the file /etc/modprobe.d/blacklist

And since then there is just one sound card in ALSA, so now audio output works well, too!

Hope it may help anyone.

Have a nice time

I have two DVB cards (TT1500 and Hauppauge Nova S-Plus).

Both contain an infrared receiver and a remote.

The TT1500 infrared receiver never worked. A device /dev/input/eventx is generated, but a "tail -f" did not output anything. So I plugged in the Hauppauge card (which does not work for DVB), and it worked for some weeks. tail -f /dev/input/event5 worked, and I could control the orbiter.

Until I finally chose to do a full install from of the LinuxMCE DVD distribution from scratch, because I didn´t get the DVB drivers to work with my old installation.

Now the infrared receiver on the Nova card also does not work any more. There is simply no output... (But I can watch record TV shows using MythTV and the PC keyboard, but not listen to it, because my sound card has now the wrong device number in ALSA...)

What should I do to find out what went wrong?

Kind regards

P.S: I really want to give it a chance and understand everything, but if I had known before that I have to spend several month without success, I would have bought a simple harddisc video recorder and kept my old windows system for my audio library... Now it is disassembled and I have my pride in making linux work for the job....

Users / how to exit playback screen in orbiter
« on: June 05, 2008, 02:56:44 am »

I play an audio file using the on screen orbiter (OpenGL with alpha blending) with keyboard and mouse (actually none of my two infrared receivers in my DVB cards work today).

But how do I return to the main menu? The ESC key does not work, and there is no back button I can click on! I can select a different song on the selected album, and it seems to play (audio does not work as well).

Is this a known bug in the OpenGL orbiter? Or do I have to use something else than keyboard/mouse? Does it work for anyone?

Thank you and Bye


perhaps someone has an answer for the following question:

I have a cmedia PCI sound card with optical output, and two DVB cards (Hauppauge Nova S-Plus, TT1500). I installed the system with just the sound card and one of the DVB cards. Now, after plugging in the second DVB card, the correct sound card is card number 2 in amixer - and I don´t get any output from LinuxMCE.

I want to change the order so that my sound card is card number 0 again. Do I have to deal with "modprobe.d/alsa-base" or with "udev/rules.d/..." or both?

I am simply confused - and every article that I read in the internet leaves me alone with figuring out which module belongs to which device - which I don´t even know.

I hope you can help me with a driver problem... I already searched the internet and as far I can read that both of my cards should work without doing anything manually...

I have two DVB-S cards: A Hauppauge Nova S-Plus PCI (should work with cx88, budget-ci) and a Technotrend 1500 PCI (ttpci).

The Hauppauge card is recognised during system startup, but there is an error:

linuxmce@dcerouter:/dev$ dmesg|grep dvb
[   38.642514] cx88/2: cx2388x dvb driver version 0.0.6 loaded
[   38.642520] cx88/2: registering cx8802 driver, type: dvb access: shared
[   38.683307] cx88[0]/2: dvb_register failed (err = -22)

It is trying to do something with the TechnoTrend card as well:

[   39.013102] saa7146: register extension 'budget_ci dvb'.

The Technotrend card I wanted to set up with "sudo modprobe dvb-ttpci" - after that dmesg shows:

[  709.602894] saa7146: register extension 'dvb'.

But after all, The Hauppauge card only shows up as /dev/video0, and there is no directory /dev/dvb. udev is running.

I am now using the 7.10 release. I already tried downloading and installing the latest V4L drivers - no change.

HISTORY: With 7.10b3, the TechnoTrend card was working. I bought it because the Hauppauge card did not provide /dev/dvb, but after finding out that the infrared receiver of the TT card did not receive any signals I added the Hauppauge card again just to be able to use the infrared control. After putting it in, the TT card still worked, and I could use the Hauppauge infrared receiver. Since update to 7.10RC3 I have the problem described above... My goal is to make both cards work with DVB, and one of them with infrared, but I would already be happy if one of both DVB cards worked.

Any hint?


It is about general driver installation procedure, which I just don´t understand.

My LinuxMCE 7.0.4 finally seems to be installed very well. But it did not recognice my hauppauge WinTV Nova S-Plus PCI card. I read in the internet that this card is supported, including the remote control interface. So I tryed to install the driver - and this is how I do it:

- I open the LinuxMCE Admin Website
- I go to "Drivers"
- I don´t know if it is "Interfaces" or "A/V Equipment". According to the documentation, none of the two matches what I have in mind, because under "Interfaces" there is just mentioned everything else but TV cards, and under A/V equipment, there is just mentioned external devices...
- OK, so I choose "Interfaces" because every other choice seems to be worse. Then I click "Add device". The window "Pick device template" opens. I select "Hauppauge" als manufacturer. For "Device category", i choose "-Please select-", then "apply filter". In the dropdown "Device template", 11 available drivers appear. But none of them matches the driver I always read about in the internet:  ISL6421   CX24123  CX88_DVB. So I decided to try every single one of the listed options...
- After selecting "Pick device template" the window closes. But the list of installed interfaces just stays empty. I try again and again with different device templates, but always the same.
- I click "Show devices tree" in the left frame. There some of my selected drivers appear, but not all at the same place. Most of them appear under "CORE" (f.ex. lircms.conf.hauppauge), one (Hauppauge A415-HPG) appears beneath CORE, as top level device.

So I finally think that I just haven´t got it. But in the Wiki documentation, there is no driver installation tutorial, no FAQ entry on general procecure of driver installation, and no normal chapter as well. This is why I decided to ask you here. Can you help me?

I am using a single-PC installation, Core, MediaDirector and Orbiter on the same PC.

It is a plain installation (just Kubuntu 7.0.4 Live-CD, then LinuxMCE Two-CD Installation). I just added one WLAN stick driver (AVM Fritz WLAN) in the mean time, which works well.
