Audio Distortion after System Crash

No quick fix for this. You have something blown on the circuit board, most likely the input to the main.

You only need compatible dvd player software to listen to movie dvd disks. For playing standard audio cd disks, nothing is needed since this support comes built in-to the OS, (Windows XP or higher)

The problem is in the audio driver or output stage which is normally an ic semiconductor, it is recommended that a technician look at the stereo to assess cost.

According to page 24 of the manual, it delivers 11 Watts RMS (route mean squared) per channel into 8 ohm speakers.

Elsewhere in the manual, you'll see references to "15 watts per channel" and as much as "25 watts per channel". The 15 watt value is valid when putting up with some 10% THD (total harmonic distortion), this value is 11 times higher than the .9% THD value given for 11 watts per channel. You tolerate .9% THD now, but you wouldn't want to listen to anything with 10% THD. The 25 watts per channel is what they call "Music Power". Watts is an electrical term, "music power" is not. You could use it to compare other devices that only offer "music power" values, but the best indication of how it will perform is based on watts in RMS, into an 8 Ohm load (most speakers are 8 ohms). The lowest THD values are best.

From the manual:

AUDIO POWER SPECIFICATIONS
POWER OUTPUT AND TOTAL HARMONIC
DISTORTION:
With 8 ohm loads, both channels driven, from
70 - 20,000 Hz; rated 11 watts per channel
minimum RMS power, with no more than
0.9% total harmonic distortion from 250
milliwatts to rated output.

I hope this helped!

I have the exact same problem with my acer aspire one. Just recently is started distorting with a mechanical sound...skipping on the videos and making it impossible to actually listen to anything or watch any videos. I thought it might just be an isolated problem until i noticed it happening during startup, etc. I have not found a solution yet but am updating the audio driver. Let me know if you resolved this issue! Thanks!

Hello,

How much memory do you have in your pc? Sometimes if you are running windows and media player, your memory is streched if you don't have alot on board. I recommend going to 2GB if you are running Vista.

Good Luck

check your buffer speeds. take them from the highest and lowest on sample rates. make sure your ram fits the bill.

Try to download updated audio codec for your system.
Go to this link:

Download it. When a box appears, Click Run button. Your vote is highly be appreciated. Thanks in advance.

Best regards

Does it display any message like "Protect" or something similar? Do you hear a relay click on then off?

Did the amp just not power up one day or did it stop working while you were listening to it? Finally, do you have teenage kids who might have been listening to your receiver and would have "neglected" to tell you that after listening to their music it suddenly stopped working?

It could be an internal fuse but chances are its something that requires a technician to repair (like the output transistors).

The sound has forsaken you because you use it unsubtly.  Take all-caps off and say whether you had sound before, whether installing the audio drivers worked, whether your speakers work when connected to a stereo output, whether your mixer on the computer is configured to do Optical-Out only; go listen to some piano auditions at various levels of ability, down at music academies and universities; play some Van Gelis through some homemade distortion filters; run some mashup software on MIDI files and crank that through midi boxes until you can get something listenable.  Break it down.
