[linux-dvb] DVB-c sound problem

["Gerhard Steiner" <steiner@mail.austria.com>]

Hello,
I tried the latest driver vom Klaus's HP together with my
Hauppauge DVB-c 727 card.
There was no sound. I hab to turn on the volume on my tv-set
to the max to get some sound.

Meanwhile I found out, that there is a function called
SetVolume with the file av7110.c where the volume is set.
The first call of this funtion is made with
av7110->adac_type==DVB_ADAC_TI (default value).
But every call after that (by vdr 1.1.x) to set the volume
is made with av7110->adac_type==DVB_ADAC_CRYSTAL!
The osd shows me, that the volume has to raise, but nothing
happens.

Then I hardcoded, that the function SetVolume is called
everytime with av7110->adac_type==DVB_ADAC_TI and now I am
getting "normal" sound. The volume isn't adjustable
(although the osd shows me that), but that's ok, since my
tv-set changes the volume.

Within the initialisation of the driver there is a block
like this
        if (av7110->saa->card_type==DVB_CARD_TT_SIEMENS) {
                VidMode(av7110, vidmode);

	        /* remaining inits according to card and frontend
type */

                if (i2c_writereg(av7110, 0x20, 0x00,
0x00)==1) {
                        dprintk("av7110%d: Crystal audio DAC
detected\n",
				av7110->saa->dvb_adapter->num);
                        av7110->adac_type =
DVB_ADAC_CRYSTAL;
                        i2c_writereg(av7110, 0x20, 0x01,
0xd2);
                        i2c_writereg(av7110, 0x20, 0x02,
0x49);
                        i2c_writereg(av7110, 0x20, 0x03,
0x00);
                        i2c_writereg(av7110, 0x20, 0x04,
0x00);
                }

Is it possible that "i2c_writereg" does not work correct on
my card?
It seams, that there is no other place where
av7110->adac_type is changed.
Could it be possible that my card doesn't have this CRYSTAL
ADAC?
Does anyone have the same problem?
Could anyone help me please?

Thanks
Gerhard
