Robert,
I have a fix that Martin is (rightly) not happy with here:
http://linuxtv.org/hg/~awalls/v4l-dvb-bugfix/
if you could test it out and let me know if it make the problem go away,
that would be great.
Then as a second step, if you can normally reliably reproduce the tinny
audio, look to reduce the delays in this part of the patch:
http://linuxtv.org/hg/~awalls/v4l-dvb-bugfix/rev/7753cdcebd28#l2.11
I would appreciate it. I was thinking 10 msec for the first msleep()
and 140 to 100 msec for the second msleep.
The easiest way to test it is:
1. Download:
http://linuxtv.org/hg/~awalls/v4l-dvb-bugfix/archive/tip.tar.gz
2. untar
3. Change into the directory and build:
cd v4l-dvb-bugfix-blahblah/
make
4. Back up your current modules in /linux/`uname -r`/kernel/media
if you want to roll back.
5. Then install the modules as root,unload any running modules, and load
the new ivtv module:
cd v4l-dvb-bugfix-blahblah/
make install
(kill the mythbackend or anything else that has the devices open)
make unload
make unload
modprobe ivtv
And you're ready to test.
Thanks,
Andy
