I have same tv dongle on ACER ASPIRE ONE and I got it work in this mode:
1. compiled and installed the hg version of em28xx-new driver (doh! i needed
to install kernel sources and compiler on 8GB SSD :( )
2. compiled and installed modified tvtime (doh! other developement pakages
to install ... :( :( )
3. DELETED
/lib/modules/$KERNEL_VERSION/empia/{em28xx-audioep.ko,em28xx-audio.ko}
4. before starting tvtime, i load em28xx-aad module:
modprobe em28xx-aad.ko tvtime -d /dev/video1
that was a good work from your side. Actually there's an installer
package available for the Acer Aspire One.
I will ask the customer if he wants to release it. The aad driver is
not alsa compatible and will only work with
that patched tvtime version. Without the alsa driver sources which are
used by Acer I don't see any other way
how to get analog audio work at all with that tiny notebook.
So just as a reminder, the aad driver is good for the Acer Aspire One
without having to update anything that's
available, the em28xx-audio driver should be used on real hosts.
Question:
if i have the dongle connected at the boot kernel detect it as /dev/video0 ;
otherwise video0 is the uvcvideo webcam... is there a way to force a fixed
name or to discover WHAT device is a device?
tvtime should be patched in order to figure out the right node for it...
eeetv on mcentral.de already does auto discovering of available empia
based devices.
I might add that code to the tvtime version there..

The only way I get sound is if I load the driver before plugging
the device, and even then I sometimes need to start tvtime or
mplayer more than once. If the driver was not loaded before
plugging the device no number of application restarts will produce
sound.
I did some more testing:
If I plug the device without modules loaded so driver loads (which
leads to no sound) then unload modules, then load modules again - all
with the device plugged - I will still not get sound.
If I load modules without device plugged, then plug device (in which
case the sound works) unload the modules, load the modules again -
all with the device plugged, I continue to get working sound.
Any time I write working sound I always have to stop and restart
tvtime/mplayer at least one time but usually two times. This also
holds true after unloading and reloading the driver.
For no sound cases I've tried restarting tvtime 15 times.
dmesg output is attached from when modules are loaded automatically
on device plug, and from when modules are loaded before device is
plugged. Including diff.

[Em28xx] modified tvtime doesn't work on Ubuntu 8.10
It worked well on previous (Hardy Heron) Ubuntu, but since upgrade it stops work with an error Access type not available (AFAIK it is from the part of tvtime which processed the sound. If there is no active channel (i.e. when the tuner is not tuned) - and so, when all sounds is muted, all is right. I means - it simple shows the blue screen with some OSD. But when an attempt to make a sound happens - it crashes. If originally there was a tuned channel - it crashes in about one or two seconds after start - at the moment when the picture appears on the screen. And - if I unload em28xx-audio and load em28xx-aad instead, this is no difference (same crash with same message) Running tvtime as root (bad idea, by the way) also make no difference.

Re: [Em28xx] Grabshow 100 with em28xx
Hi Németh. Thanks for sticking to my prob! It always happens... The steps are a bit complicated... I installed Zoneminder (latest release on zoneminder.com), which needs quite a few additional packages to my standard distro (openSUSE 11.1) to work. I then added a new Monitor with the source /dev/video1 and resolution 640*480 (also tried different ones). Then, make it Active and click on it, and it should display the video source. But it just displays a black screen and the log files (in /tmp/) report errors. What I mailed you is dmesg output.

To debug this problem it would be useful if you can set the CONFIG_* parameters I specified (run make menuconfig from the linux source directory (usually /usr/src/linux) and press the / key so you can search for the CONFIG_* parameters. Then the kernel configuration is saved to a file named .config. There should be a description somewhere which describes how to build Linux kernel. I finally managed to compile my kernel again with the parameters you gave me, took my quite a while. Now uname -r reports 2.6.27.7- debug2, means what I did worked.
