Atari800/5200 emulation faint humming sound while running a game?
-
I finally got atari800 set up to play seamlessly with a controller with buttons mapped properly. Now I am fine tuning the experience. One thing I have noticed is a faint low Hz humming sound that is consistently present whenever a game is running. It's not there in the menu.
It's a similar sound to if you take a 3mm speaker jack and touch the metal to something else conductive, like your skin, and it makes a humming sound in your speakers. That's what it sounds like.
I was wondering if anyone else has had this problem and has found a fix? I tried playing with the sound settings in the atari800 emulator but nothing gets rid of it in there. It's subtle, so I am perfectly fine to just play with it. But if there is a way to get rid of it, that would only improve the experience.
I am going to play around with the sound settings/ speakers on the TV on which I am playing and see if it has any impact.

@pjs Please do not post a support request without first reading and following the advice in https://retropie.org.uk/forum/topic/3/read-this-first
No idea if you are running on a Raspberry Pi or pc, what version of retropie etc etc.

@BuZz My apologies for forgetting the rules. I have edited my original post to reflect the rules.
-
@pjs Did you try any of the steps mentioned here - https://github.com/retropie/retropie-setup/wiki/sound-issues#white-noise-fix (option 4 or 1 may be the best - and making sure volume is up).
-
I forgot to ask Are you using analogue audio or HDMI? - if HDMI it's likely to be emulator related (apart from the volume change). I assumed you were using analogue audio out ?
-
@BuZz I just tried 1, 2, and 4 from that list. The humming is still present while running games in atari800 (noticeable soon as the Atari boot screen appears and remains until either the emulator menu is launched or the rom is closed. It is very faint. I am about to try some settings on the TV.
-
@BuZz I am using HDMI audio. I noticed #4 seemed more regarding the headphone jack but tried it anyways. I have reverted the /boot/config.txt back to default once I tried those.
Also, I will mention that audio is perfect in all other systems, it is only the atari800 emulator where this is present.
-
@pjs must be related to the emulation etc.

FYI I have same problem but in RetroArch that recently gained atari800 support, different platform - NVIDIA Shield TV (Android). I have decided to file a bug report at: https://github.com/atari800/atari800/issues/13
