PVR150 PAL composite + tuner audio

Hi folks,

I have this issue with PVR150 PAL (no MCE):

- when I load ivtv driver (I load tveeprom before it) with "tuner=52"
parameter, I get no error messages

- when I play from /dev/video0 from composite input, I get with 0.3.2b
version of driver the input sound mixed with tuner sound (jerky noise if
tuner is *untuned*)

- with 0.3.1a + Ulf's patches I get no sound at all.

Kernel version is 2.6.7 with Con Kolivas patch set (-ck1)
FW is extracted from original CD.

Please reply if you have to give advice.
Thanks.

Mario Vigliar

Here's what I do to get my card working (also pvr150 pal, not mce):

modprobe tveeprom
modprobe videodev
modprobe cx25840 i2c_enable=1
modprobe tuner
modprobe wm8775
modprobe ivtv ivtv_std=2 tuner=52

Best regards

Same thing. When I switch to Composite input with "ivtvctl -p2" I get a
noise (maybe the tuner voice) together with the line input audio.

What version of kernel/firmware do you use?

Regards,
Mario

I found the trouble: I tried with 0.3.2a with Ulf's second patch (the
one conteining the mixer_input tweak) and set the wm8775 with mixer_input=2.

In this way I eliminated tuner audio mixing and got the correct line in
audio signal.

Thank you all anyway.

Ok, I've never tried the composite input, only tuner.

> What version of kernel/firmware do you use?

I'm running gentoo here. And when I installed the ivtv I installed the
ivtv-tools and firmware via gentoo's package-management (emerge/portage)
and then installed ivtv-0.3.2b after that. So I don't really know what
firmware is used, but md5sum is:
---------------------------------------------------------------
305dba74bbe5905447add8883f3ecb68 /lib/modules/ivtv-fw-dec.bin
6e2012d919fa48811c27e25e54a0a5dc /lib/modules/ivtv-fw-enc.bin
a6f6a90a3be338cdb89d59e835798408 /lib/modules/HcwMakoA.ROM (taken from
the pvr150 CD)
---------------------------------------------------------------
Kernel version is 2.6.10 + gentoo patches (gentoo-dev-sources-2.6.10-r4):
http://dev.gentoo.org/~dsd/gentoo-dev-sources/releases.htm

After I've activated the card, it runs (with the tuner) ok for a while and
then the sound disappears completely.

It seems that the drivers need some tweaking yet...

Best regards

Second patch? Is this integrated with the 0.3.2b? I can't find
mixer_input, so it seems not. Where do I find the second patch? TIA.

You're welcome/Siete benvenuti!

(I used google translate so you know who to blame if the above italian
words don't make sense :-)
