[RC1] TT-Budget/WinTV-NOVA-CI is recognized as sound card

[nite_man]

Hi,

Recently I upgraded my LMCE 0710 Beta 4 up to RC1 (I don't think that there is a some significant difference between RC1 and RC2). After a first reboot it was everything fine - sound was presented, DVB card is recognized as DVB, VDR worked fine and showed Russian EPG correctly. But when I booted my core next day I found that DVB card is recognized as sound card:

Code Select Expand

linuxmce@dcerouter:~$ cat /proc/asound/cards
0 [Audiowerk2     ]: aw2 - Audiowerk2
                      Audiowerk2 with SAA7146 irq 16
1 [NVidia         ]: HDA-Intel - HDA NVidia
                      HDA NVidia at 0xfe020000 irq 20
I fixed issued with sound just making NVidia as default sound card in the system. But DVB card is till is not recognized as DVB. I can see that message in the dmesg:

Code Select Expand

[   81.311527] saa7146: register extension 'budget_ci dvb'.
but the rest messages which usually present are missed:

Code Select Expand

[   81.311616] DVB: registering new adapter (TT-Budget/WinTV-NOVA-CI PCI).
[   81.351799] input: Budget-CI dvb ir receiver saa7146 (0) as /class/input/input5

On the fresh RC1 installation it works ok. Any suggestion how to solve that?

Thanks in advance.

I think somebody else is having this same problem: http://forum.linuxmce.org/index.php?topic=5267.msg31639#msg31639 would you mind lending him a hand?

The only thing that comes to mind about your issue is that maybe not all the right kernel modules are loaded automaticly at boottime?

[nite_man]

Hi Zaerc,

Already post there how to solve problem with sound. Your guessing sounds reasonable. Will dig the boot procedure to find why DVB is not recognized properly.

[Zaerc]

Thanks for addressing the other problem, wasn't sure you had seen it and it sounded the same.

I've just had a look at my system (which is obviously different), maybe it helps a bit to compare.
I think these are the relevant lines from lsmod:

And I see this in dmesg:

# dmesg | egrep -i '(dvb|saa)'

And I have this in /dev/dvb/adapter0:

I had to compile the latest v4l-dvb from the repository myself to get the card going though, so I'm not sure if this has any relevance to your situation at all.

Thanks, Zaerc, for your info. I suspect it somehow related with new drivers in RC1. I used the same configuration a few monthes with different beta versions and everything worked fine. Now I have the same problem on the fresh RC1 installation. Will try tonight RC2.

[nite_man]

After discussion in the linux-dvb mailing list found what is causing that:

Complain to the developers of the Audiowerk2 driver for this:

| static struct pci_device_id snd_aw2_ids[] = {
|       {PCI_VENDOR_ID_SAA7146, PCI_DEVICE_ID_SAA7146, PCI_ANY_ID, PCI_ANY_ID,
|        0, 0, 0},
|       {0}
| };

This will grab _all_ saa7146-based cards. :-(

So, Audiowerk2 should be added into black list. Will try it tonight.

[Zaerc]

And I thought you actually had one of those cards.  Way to go Audiowerk2 developers!

To blacklist a module simply add a line to /etc/modprobe.d/blacklist like:

Code Select Expand

blacklist <module>

[Zaerc]

I've just ran into the exact same problem myself after a fresh install of 0710rc2-amd64, the module is called snd_aw2.  I probably didn't notice earlier because I think I added the dvb-t card lateron.  Anyway, to fix this problem from the command line in, a nutshell:

Code Select Expand


echo "blacklist snd_aw2" >>/etc/modprobe.d/blacklist
reboot


Thanks for doing all the legwork in sorting this out nite_man!
