Crackling/Popping Sound regardless of output method! USB-Soundcard.
-
Hello again... anyone tried this out:
Troubleshooting!
If you're using a Raspberry Pi and notice the output isnt totally clean, some USB Audio
adapters don't like USB-1.2 and produce crackling in the output. You can work around the
problem by adding dwc_otg.speed=1 to /boot/cmdline.txt and setting the USB ports to USB-
1.1 mode.?

@yuke for the headphone jack in /boot/config.txt i think it is:
disable_audio_dither=1 -
Hello, im using
disable_audio_dither=1
and also
audio_pwm_mode = 2
I dont understand why the usb soundcard jack is exactly the same mess as the pi 3.5mm jack. I dont know much about software and hardware used when creating sound but this doesnt make sense to me ... everyone else is claiming to solve all the sound problems with the use of an usb soundcard...
Can i trash my usb soundcard if it try out forcing usb 1.1? (troubleshooting quote from my last posting)

Not likely. You can try removing all the sound related settings from you
config.txtfile and re-try to see if the sound improves when using the USB soundcard.
What USB soundcard are you using ? -
I had the same issues where an USB soundcard wasn't better then the build in headphone jack. But that was after I tried different ways to enhance the headphone jacks output. After I did a clean install of Retropie, the quality was way better.
It almost looked like that the clean install noticed the USB card and adapted the settings.Another thing I noticed, when I got my second Pi last month, was that any extra cable reduced the quality of the card. I had it plugged in into a cheap, passive hub with a short cable at first. And I could hear it buzzing whenever I accessed my hard drive or on heavy network traffic.
On my second Pi I was able to plug it directly into one of the USB ports of the Pi, and now the quality is almost perfect.I don't know if this is helpful in any way, because I changed nothing in my setup other then having the card connected directly to the Pi.

What do you mean by "wasn't better" ?
I dont have problem with background noise or low volume for example but i have crackling/popping sounds (especially with high tunes). I dont want to reinstall it without being sure it could help...sadly my game library is also on the SD card...
Im using the one of my HyperXcloud2 Headset. It has support for PS4, Mac, Linux and Windows
Also ordered a cheap one (advertised with retropie support) which isnt here yet (waiting for it before doing something drastic)

@yuke I meant that I thought buying an external soundcard was a waste of money, because there barely wasn't any difference between the build in jack and the one from the soundcard. But like I said, that was when I already messed around with different settings to fix the issues with the build in jack.
I'm using a Speedlink Vigo by the way. -
Yeah but what sound issues did you have?
And btw i was testing out three different 3.5mm cables between 20 and 50 cm and there was no difference at all. I think everything under 1 meter will be ok...
-
@yuke Oh, i was having random crackling sounds and constant buzzing. After the new installation, the crackling was gone, but there still was a slight buzzing.
And I don't think that the length of the 3.5mm cable matters, mine is 3 meters. Although I'm only using some cheap in ear headphones so there still might be some noise but I'm happy now. -
@yuke If your sound card is being powered by the pi it could well be a simple ground loop. You can get a 3.5mm jack ground loop eliminator which would solve that for a few quid on eBay. You’d need to try powering the sound card from a separate power supply and see if that confirms?
-
thats a good idea i guess and worth trying out
-
in case i decide to reinstall my pi2scart retropie image:
this is the way to go for usb backup (+ starting games from usb stick in the fture)?

ground loop eliminator
that saved me a couple of times now
-
ok funny thing i noticed while backupping my sd card to usb.
the sound problems got worse while the data was transfered to my usb stick. what does that mean?
-
Ok can please anyone just tell me if my Pi is just broken?
I found an hdmi splitter in the darkest corner of my room and did output the sound over its stereo jack (Its and HDMI -> Component/RCA/Stereo-Jack Splitter) and i still have the sound issues.
Anyone? Please?
-
retropie image reinstallation helped. what can i do to prevent this from happening tho?
-
Well. Here i am again. Was playing the whole evening and the soundproblems have started again. Its like a degradation over time or something. I know it was perfectly fine after reinstalling the image, was testing it for quite some time out.
What can be the reason for such a weird problem? Like gimme anything you have. Far-fatched or not i dont mind.
