Hi,
The context is to get Medion MD7134 form Aldi-PC MD8008 to work with
saa7134 driver under Linux. There are different types of that card out.

That was the hint I needed to get closer. By editing this file, I got
stereo sound and muting works now. Inc/Dec Volume works limited, id
est "Volume: 0%" is lower, but not muted. Therefore I can currently
not switch between mono/stereo lang1/lang2 (got both languages in
stereo, if available -- nice effects !
Simultandolmetschertrainingsprogramm is a german compound noun for
that "feature")
I got two different Card-configs working as described. The original
values are commented out.
[SAA7134_BOARD_MD9717] = {
.name = "Tevion MD 9717",
//.audio_clock = 0x00200000,
.audio_clock = 0x00187de7,
//.tuner_type = TUNER_PHILIPS_PAL,
.tuner_type = TUNER_PHILIPS_FM1216ME_MK3,
//.need_tda9887 = 1,
.inputs = {{
.name = name_tv,
.vmux = 1,
.amux = TV,
.tv = 1,
[...]
In that config, tda9887 is not needed, but in the next one, I only get
noise without it:
[SAA7134_BOARD_MD7134] = {
.name = "Medion 7134",
//.audio_clock = 0x00200000,
.audio_clock = 0x00187de7,
.tuner_type = TUNER_PHILIPS_FM1216ME_MK3,
.need_tda9887 = 1,
.inputs = {{
.name = name_tv,
.vmux = 1,
.amux = TV,
//.amux = LINE2,
.tv = 1,
[...]
I dont really know what I've done. The tuner-type should be correct.
"amux" seems to be something like the input line of the TV-cards audio
mixer device. What "audio_clock" is and tda9887.o does -- hmmm. I just
recalled that sound worked with amux=line2 and audio_clock=200000 --
probably resulting from the initial settings (left unchanged) !?
I go on studying tvaudio.c. Together with the "mixer=video" in xawtvrc
workaround, I am happy as long as there is no two-channel audio (two
languages).
Dirk.
