@RSquaredPi Hi, the ControlBlock supports up to 7 A. If you do not have any additional accessories connected you should be good to go.

@RpiBeginner You could try to add this to the file /boot/config.txt to improve the analog sound from the 3.5 mm jack:

audio_pwm_mode=2

It changes to a new (still experimental?) audio driver. My audio via the 3.5 mm jack improved significantly with it. It won't change anything for HDMI audio, as I guess it won't for an external USB audio card which should have its own drivers.

You can find this and some other tips at https://github.com/RetroPie/RetroPie-Setup/wiki/Sound-Issues under "White Noise Fix".

This worked great for me, although I did order a USB sound thing. I can try that out too. Thank you

@michael40475 said in Audio not working? How to fix problem??:

can I please get very detailed advice on how to fix this issue? Thanks so much in advance.

Not unless you provide very detailed descriptions of your entire setup. That only makes sense, right?

@trailjacker said in Lightning Bolt / General Electronic Question:

Many users worry that that they may "supply too much power" by using a higher rated supply.

Yes, because they do not understand that in electronics, a device will draw the current that it demands. For example, I buy a green LED. It requires 25mA to illuminate. I decide to power it with a 3A power supply. The power supply laughs at it and delivers the 25mA with 2.975A spare capacity to power other things like a Pi.
