Re: Pi-to-Pi Low Latency One-To-Many Video Streaming

Have you investigated "Motion" surveillance software on a Pi? There are many tutorials - here's one: https://www.instructables.com/id/How-to-Make-Raspberry-Pi-Webcam-Server-and-Stream-/ I used this to quickly setup a number of webcams, each serving webpages to anything on the network (including othe...

Re: Just about to buy Raspberry Pi for Media Centre and would appreciate help

You will probably find you don't even need a keyboard/mouse if you connect your new Kodi system to a TV with HDMI-CEC (as most of them have). This is because the TV's own remote control will control the Kodi system (via the HDMI cable's back-channel). This is all built-in - don't worry about it - ju...

You need the MPEG2 Licence Key - it's needed for ANY DVDs - whether "commercial" Macrovision-encoded DVDs (or whatever) or not. "Protected" or "unprotected" doesn't enter into it. DVDs ALL use MPEG2 and play vastly better with the hardware decoder enabled. The licence is just pennies anyway. I use a...

Re: Background Noise on Audio

ISTR talk of dither being applied to make the approx 11 bit PWM DAC analogue audio out sound a bit better. Is that enabled and present even on a digital output from the RPi? If it were the case that dither is causing the OP's noise, wouldn't everyone taking sound out of the Pi have heard it too?

On a related note:

Does anyone have any evidence of "image burn-in" on the (presumably) CCDs inside these cameras, when used on a static image indefinitely, like in a security camera application?

Re: Background Noise on Audio

Is it possible that the audio file you're trying to play has been digitized at a very low audio level? To test/eliminate this possibility, do you have any other (non-Pi) device that can feed the same audio file to your amp? Is there an analogue output you can try on the HiFiBerry? Which maybe DOES h...

Re: Background Noise on Audio

The TYPE of noise might help identify its source. Hiss? High/Low? Hum? Crackling? Buzzing? Is it affected by the volume control? If you have more than one place where you can adjust the volume, maybe your "gain staging" is at fault. If what you're actually hearing is the noise floor, try turning the...
