TOPIC: Distorted sound/Processor related?

Distorted sound/Processor related? 6 years 4 months ago #480

When the Amulet music screen is showing or the Amulet TV/Movies screen the sound will warble and the response time is a little slower then when just a tv show is playing or only music is playing.
I have a feeling this is processor related. I am using a AMD 64 x2 5600+ 2.9ghz and it just may not be powerful enough to do speech and record tv and show the Amulet graphics.
Anyone else experience this?

This does sound like a CPU related issue, but in general, the AMD 64 x2 should be plenty fast enough for Amulet. For example, on my Core2Quad Intel Q8800, I only see CPU usage of around 20-25% when running the Amulet music page. How much RAM is on your system?

Can you check CPU usage in Task Manager and see if any of the ehExtHost.exe processes are averaging around 40-50% CPU usage? If so, note the Process ID (you may need to enable the PID column under View / Select Columns). Then cross-check the process ID against the most recent Amulet log file in C:\ProgramData\Amulet Devices\Logs and you can identify which Amulet Module is responsible.

Is it possible your DirectX graphics drivers have been disabled, so the system is using software rendering for the graphics effects in Media Center? Run DXDIAG from the Desktop Start menu, select the Display tab, and make sure both DirectDraw and Direct3D are shown as Enabled.

Thanks,

Eddy

The system has 4GB of Ram and is using on board graphics.
I tested the Amulet on a machine with a video card and got better results.
I think I need to add a video card to the system as the embedded graphics are giving me trouble with HDCP errors. DxDiag shows everything enabled.
I imagine the Ceton card is using a lot of resources also.

I think it would definitely be worth adding a video card, even a cheap $30-$50 model.

Onboard video cards often share the same memory architecture as the main system RAM, so the audio and video will be competing for access to the motherboard memory. If there is a lot of animation, this becomes much more intense. Video access generally gets priority over audio, which might explain the sound interference you're hearing.

I added a video card and the difference is noticeable, most/all distortion is gone and video performance is improved.

The video card also solved a problem I had with my Yamaha receiver and HDCP. Prior to using the card when switching sources the HTPC would not sync; that problem has now disappeared
