Start pulseaudio with realtime and no CPU limit

[tweinreich]

For me adding the --realtime and --no-cpu-limit to init.d/pulseaudio script as startup parameters solved some of my issues with lagging output (I may have to try a newer Pi and/or a decent sound card).

Tested with:

• Raspberry Pi 2011.12
• Raspbian Stretch
• No extra sound card / interface
• iPhone 5s (AirPlay)
• Motorola Moto Z (Default Bluetooth)

Have you done that to stop the chopping that happens when the onboard wifi is enabled while using WiFi at the same time?

@otmpp If I'm correct Model A Revision 2.0 doesn't have onboard WiFi. I used an Edimax USB WiFi Adapter. It was activated the whole time though. Did you experience any issues with this?

Ahh yes I see what you mean. For bluetooth I have only ever used the Zero W or the 3B or 3B+ and I've used the onboard WiFi and Bluetooth. The only way which I have that I can stream bluetooth music reliably is by disabling the onboard WiFi since they interfere with one another. I have heard that you can use a usb WiFi card like you have and then like that it works. The way I have used his scripts is either on the Zero W or 3B. I have only tested the Bluetooth only installation and only once I disabled the onboard WiFi could i then stream audio well

@otmpp ok that's not fortunate for me as I wanted to use WiFi because I hoped it would be more reliable and can cover a greater area. Thank you for sharing your experience.
