I recently switched my frontend to a Zotac Zbox with an Atom 330 and Ion<br>
GPU. I've worked out most of the issues, but still have one remaining<br>
problem that I'm having a hard time debugging.<br>
<br>
The audio has very frequent dropouts, where there will be no sound for a<br>
fraction of a second. These little hiccups are sometimes bad enough to be<br>
unwatchable.<br>
<br>
- The program seems to be okey. I've played the same video on my TV via<br>
DNLP and it played perfectly.<br>
- The video shows no interruption, only the audio has problems.<br>
- Audio/Video output is over HDMI to a Yamaha soundbar<br>
<br>
In the past, I had used this hardware for a myth frontend. At that time<br>
my display was 720p, it's now doing 1080p. Could 1080p be stressing the<br>
Ion?<br>
<br>
I tried running mythfrontend with "-verbose audio" and didn't get any<br>
audio logs. Any pointers on how to debug the audio issue?<br>
<br>

I don't have an Ion box, but I do have an Ion2. I had a few problems, but<br>
finally got things working properly. I did have audio dropouts, especially<br>
when browsing the EPG. Some things I did to resolve this was...<br>
<br>
"On the frontend, if you go<br>
into the settings -> audio, you choose what audio card to use and the<br>
capabilities of that card (IE: dolby digital, plus, dts(?), things like<br>
that). In there, there's a checkbox for '5.1 upmix'. "<br>
<br>
Disable that 5.1 upmix.<br>

<br>
The other thing I did was change the "Apperance/Theme" to OpenGL. I think<br>
this fixed a lot of the issues too. Finally, I followed the wiki page for<br>
the 'vdpau' stuff.<br>
<br>
Also, make sure you're using the nvidia driver and not the open source<br>
one. I even had issues with the nvidia driver included with mythbuntu.<br>
It's a pain, but I have to reinstall the driver by hand everytime I do a<br>
kernel update. If it's of any help, I'm using the following driver on my<br>
frontend...<br>
<br>
NVIDIA-Linux-x86_64-340.76.run<br>
<br>
This is for an Ion2, so I would make sure your Ion is supported with this<br>
driver version.<br>

Strange. Installing the nvidia driver on a stock Debian, following the instructions, sets it up as a DKMS build[1]. This means that it is automatically rebuilt every time there is a kernel update. No tinkering or pain involved.<br>
<br>
Of course, Ubuntu may do things different.<br>

I've just experienced a few glitches with the video driver after a kernel update. I don't know if it's my junky receiver or the video driver, but it seems like it looses sync.

Or, maybe it's something else.... </div><div><br></div><div>In any case, I just reinstall the driver for the video card after the kernel updates to prevent possible future problems.</div><div><br></div><div>Mike</div></div><br></div></div>
