Title:
Some tuner cards will not resume after suspend/hibernate
Status in “linux” package in Ubuntu:
Expired
Bug description:
Binary package hint: mythtv
Hi. There seems to be an issue with some tuner cards not waking up
after a suspend or hibernate. My motherboard is an Asus A7V400-MX, and
I've tried it with the Hauppauge WinTV PVR-150MCE PCI tv tuner card,
as well as the Hauppauge Wintv-PVR-USB2 usb external tuner card. I
have also tried the PCI card in my brother's nForce board, with the
same results. (These boards resume from suspend/hibernate fine
otherwise.)
After resuming, using the command "mplayer /dev/video0" will not
display a TV channel window at all, as it is does after a fresh
restart.
I believe it just may be certain motherboards, as plenty of other
people have these cards and seem to be fine with them. I'll try it on
other boards.
Superm1 on the ubuntu-mythtv IRC channel suggested going into
/etc/defaults/acpi-support and adding a few modules to the module
list, such as ivtv and ivtv2. This suspends the modules before a
suspend/hibernate, and resumes them upon resume. After adding these to
the file, I hibernated the machine, and using the command "mplayer
/dev/video0" displayed the TV channel window, but the entire window
was blue.
The twist: The screen is blue, but the sound is functional! Weirder
yet, when I pull up another app, such as rhythmbox, and move the
rhythmbox around, the video flickers while it redraws the rhythmbox
window, and for a split second you see the video window for the tuner
displaying a show!!!
