Hi Joerg,

can you please add your sybsystem_vendor id to this if()-case and test if this works for you? If so, please send a patch.

Having read that the 'newstruct' drivers support volume-control on DVB-C
Cards was one major reason to switch. But even with the new drivers the
volume does not in- or decease when i.e. using vdr.

What might be wrong? Or did I dream reading of this capability :-)
Annotations: I own a Siemens DVB-C rev. 1.5.
and I use the latest CVS-drivers.

Can someone help debuging?

Again answering myself:

Found this in av7110.c:

if (av7110->saa->device->subsystem_vendor == 0x110a) {
	if (i2c_writereg(av7110, 0x80, 0x0, 0x80)==1) {
		i2c_writereg(av7110, 0x80, 0x0, 0);
		printk("av7110: DVB-C analog module detected, "
		       "initializing MSP3400\n");
		ddelay(10);
		msp_writereg(av7110, 0x12, 0x0013, 0x0c00);
		msp_writereg(av7110, 0x12, 0x0000, 0x7f00); // loudspeaker + headphone
		msp_writereg(av7110, 0x12, 0x0008, 0x0220); // loudspeaker source
		msp_writereg(av7110, 0x12, 0x0004, 0x7f00); // loudspeaker volume
		msp_writereg(av7110, 0x12, 0x000a, 0x0220); // SCART 1 source
		msp_writereg(av7110, 0x12, 0x0007, 0x7f00); // SCART 1 volume
		msp_writereg(av7110, 0x12, 0x000d, 0x4800); // prescale SCART
	}

	// switch DVB SCART on
	outcom(av7110, COMTYPE_AUDIODAC, MainSwitch, 1, 0);
	outcom(av7110, COMTYPE_AUDIODAC, ADSwitch, 1, 1);

	//setgpio(av7110, 1, GPIO_OUTHI); // RGB on,
	//SCART pin 16
	//setgpio(av7110, 3, GPIO_OUTLO); // SCARTpin 8
	av7110->adac_type = DVB_ADAC_NONE;
}

and lspci reports:
00:0a.0 Class 0480: 1131:7146 (rev 01)

I think this means I cannot set any Volumelevel :-(((
