So I wake up today and do some internet browsing on my laptop.  After about an hour, I decide to listen to some music through iTunes.  I turn on my E17 and the sound is crackling and distorted just like it was yesterday, only today the settings are correct.

 

Settings:

Supported formats - none

Sample rates - 44.1, 96.0

Levels - all 100

Enhancements - none (none even listen in settings)

Default format - 24/44.1

Exclusive mode - both enabled

 

What the heck.

16/44.1KHz please. 24 bit may cause a problem depending on file, computer, software, hardware etc.

 

Try the E17 on another computer please. 

 

Can you use Foobar with WASAPI to play audio?

I typo'd.  Default format was 16/44.1.  No other computer to test on.  Testing Foobar now.

This is screwing with my head.  I downloaded Foobar and successfully played a handful of songs with no distortion on 16/44.1.  I go back to my browser and accidentally hit play on a Youtube video I had open.  The sound was no longer distorted.  The only settings changed during this process was the default format, which I switched from 16/44.1 to 16/32 to test general sound, and back to 16/44.1 to test Foobar.  Youtube even works on 32/96 now.  This is madness.

Windows Sound does not allow for 32KHz

 

There is no support for 32 bit audio nor is that a popular format if it is even a format at all.

 

Getting the right numbers makes it easier on you, me, and anyone reading this. 

 

It is strange sometimes. Try on different computers, and see if it happens tomorrow. For the time being, begin the Panda song again. I am 100% sure that it screwed up because you didn't sing the song panda. I know these things. Now come with me:

"Panda PAnda, you are the best, Panda PAnda, I'll write a check, Panda Panda Panda"

post #4745 of 6558

OK, I think I found the problem but have no clue how to resolve it.

 

Strange as it sounds, the laptop coming out of sleep mode seems to be the problem.  Everything was working fine on 16/44.1 so I decided to reproduce the circumstances that caused my amp to freak out.  Put my computer in sleep mode, woke it up, and opened a song in Foobar.  Result was distortion and crackling in 16/44.1.  Setting the format to 16/32 still resolves the problem.  As the problem in 16/44.1 seems to have resolved itself last time, I'm thinking either the computer or the amp needs a "warm up" period of sorts to accurately produce sound at any format higher than 16/32.  16/32 sounds alright but I have no idea what to do about this.

 

edit - doesn't seem to be time-sensitive.  16/44.1 isn't working for me now.  Will test more.

 

edit 2 - Found solution.  

 

1.  Turn E17 on

2.  Set default format to 16/44.1

3.  Restart computer, keeping E17 turned on through whole process

4.  Sound is clear upon restart

 

Still makes little sense to me but at least the problem is fixed.

16/32? Where are you getting an 32KHz option?

On Windows: Playback devices -> E17 -> Advanced -> Default format drop-down menu.  16/32 is the highest option.

go to: Playback devices -> E17 ->  Supported formats, and then check the boxes for 44.1, 48, and 96 as well. then go back to advanced and select 16/48.

 

I dont know what most are using, but I've been using 16/48 since I only have 256kbps AAC and 320 kbps MP3 files. I dont have any higher res files.

I give up.  Restarted my computer again to test and the distortion is back on everything except 16/32.  There's no consistency to this.  Leaving it on 16/32.

Can you take a screen shot of the 32KHz option?

Try to stay on 44.1 and not lower.

post #4754 of 6558

whats better? 6db gain with a higher volume vs 12db gain with a lower volume... discuss.

 

Edit: I just switched from 12db gain with an average volume of 20-25, to the 6db gain with an average volume of 25-30, so far the only difference I hear is that the volume steps are smaller which is nice. Sometimes on the high gain just one volume step to the next would be to big of a change. Other than that the sound seems the same once level matched. 

 

Anybody have anything to add to this subject?

I can't hear any difference, so I leave gain at 0 dB and only increase the gain if I really need to, i.e. a weak source.
