[linux-dvb] Re: Re^3: Audio/volume issues with Siemens DVB-C,especially analog module

[mi_me@freenet.de]

It seems to me that I am one of the (few ?) lucky persons whose 
Siemens DVB-C analog modul is working with sound. 

There are a couple of discussion concerning analogmodul on vdrportal.de e.g.
http://vdrportal.de/board/thread.php?threadid=11096 (in german)

Well .. in order to compare I send my configuration:

Video and audio are fine and can be displayed by xawtv even while vdr
is running. Switching from dvb to television (analog modul) and back works.
Sometimes vdr has to be convinced go on working by changing channels
within vdr. 

I haven't tried recording from analog modul. Not yet time found. 

analogtv is _not_ supporting analog modul. I checked the source and found
some code that starts integrate the analog modul. I am a sysadmin ;-) thus 
programming is not my real business ;-(

Hope to have encouraged you!
Michael
