[linux-dvb] can not control volume from VDR on my Siemens cable card PCI rev1.5]
Sorry, I have sent it to the wrong list.
I also should have mentioned that I have enabled:
export USE_DVB_DSP=1

Hi,
I can not control volume from VDR on my Siemens cable card PCI rev1.5
because of an assumption made that all Siemens DVB-C cards would
have no DSP or have a MSP3400 (on analogue modul). This is what
I guess ...
(I don't have an analogue module)
The error message from VDR in /var/log/messages is:
Aug 21 18:07:47 khlin2 vdr[9787]: ERROR (dvbdevice.c,713): Die Operation
ist nicht erlaubt
The whole issue was already discussed last december but there was no
solution to the problem. Seems Jörg gave up ... because he did not
tell what kind of DSP is on Siemens DVB-C rev. 1.5
---- beginn: ignore it should only tell that I have done my homework
----
Here is a collection of the thread:

There was another thread:
"RFC: patch for support of volume control on DVB-C+analogue-module"
http://www.linuxtv.org/mailinglists/linux-dvb/2003/04-2003/msg00295.html
which is also no solution to my (and probably Jörg's) problem !
---- end: ignore it should only tell that I have done my homework ----
The following code piece tells me that the programmers assume that every
Siemens DVB-C card will have a MSP3400 or no DSP. Am I correct in
reading
this code ???
As you also can see in this piece of code I have disabled it through /*
... */
and recompiled. I loaded the module with adac=0
Then VDR does no longer report an error but still I can not change
volume or mute !
So behaviour changed. This means to me that I/O control to sound (?) is
at least
established in the sense VDR has a counterpart to talk to. But may be in
the
code / initialisation / ... something goes wrong !?!?
The board has an internal connector to a sound card, has the "Audio
Main"
output (external to sound card), has SPDIF (coax) and Audio L and R
(Also there is a SCART whereby sound is only working if Audio Main
looped back
to Audio R/L or looped through a soundcard.)
Is there really no sound chip on this card ?
(see the list of ICs at the end)
btw: how to make use of SPDIF ?
Thanks,
Karlheinz
