Chris,
Yesterday evening after noticing the out of sync audio I went back to
version 0.3.4l (stable for me). This version does not have the out of sync.
This morning I retried verion 0.3.5m to test it with cat, dd and my own
software. No more out of sync audio.
What I notice with my system (Asus P4C800 Deluxe) is that for a new
version of the driver I have to shutdown my system and even have to
unplug the power cord and one of my, powered, usb hubs. When I restart
the system the card will start fresh. If I only shutdown the system and
do a restart the pvr cards keep some settings stored.
So the next time I will follow me really cold boot procedure to do some
testing.
Regards,
Michel

Is this just using cat? I doubt out of sync audio would ever be the
drivers fault because there's really nothing we do to alter the mpeg
stream and it's all hardware muxed, no settings to change that besides
an audio/video delay API we don't touch in the driver. Try cat and/or
dd to see if it really is the hardware doing this that way, or if already
done that then it is really odd, I'm not sure what could have caused this,
maybe someone else can think of something?
Thanks,
Chris

I do not know if this happened in a previous version of 0.3.5 but with
the m version I have out of sync audio on my pvr-350 and on my pvr-150 I
sometimes have audio and sometimes not. When I have audio on the PVR-150
it is not out of sync.
When I have audio on the PVR-150 and I change to another channel the
audio is lost again.
I use the following to get the drivers loaded (PVR-150 is first and
PVR-350 is second)
options saa7127 i2c_enable=-1,-1,1
options cx25840 i2c_enable=1,1,-1 fw_file_name=/lib/modules/HcwMakoA.ROM
modprobe ivtv ivtv_std=2 tda9887=0,0

But the worst is the out of sync audio on the pvr-350.

This uses a register containing the VBI buffer offset to be exact about
buffer
grabbing, seems much better than the old method and so far seems to not
miss
characters in vbi insertion etc...
Please check this in PAL for teletext, still trying to get it working right
and not missing characters in raw mode, hopefully this buffer offset thing
makes that happen, or closer.
