    pCP 4 Real Time Kernel vs pCP 3 Audio Optimized

    I am still running on a Rpi3 the "old" 3.22 version since it is great.
    I never used the Audio Optimize version before because of issues with Rpi3 WiFi

    What is the difference between the old Audio Optimized and the new Real Time Kernel?
    When is suggested the standard and when the Real Time Kernel?

    Thanks a lot.

    If you don't know what a RT kernel is.....then you probably don't need use it. https://rt.wiki.kernel.org/index.php...sked_Questions

    I will always suggest the standard version of pCP. If you want to tweak and tune, then try the RT version.

    Well... I know quite well what a real time kernel is.
    You could eventually say: ask to google, search the forum, etc. and this would be acceptable.

    Go back to my question: I was not asking what is a real time kernel system, rather I was asking the differences (if any) versus the "old" Audio Optimized version.

    Regards.

    The old Audio Optimized kernel was not Real Time. The current one is. That is the only change.

    Thanks for the feedback.

    Another question: in the past the old Audio Optimized version was not suggested with WiFi.
    What about the new Real Time Kernel one?
    Moreover and generally speaking, when is the new one suggested?

    Today I am running 3.22 + WiFi + USB DAC Teac UD-503, playing 24/384 FLAC without any issue.

    hi steff,

    I would only use the Audio Optimized pCP if I is was an "Audiophile who liked a little pain".

    I don't use it myself.

    The RT Kernel is only just started getting "official" status by RPF so it will be a while until that is considered mainstream IMHO.

    regards
    Greg

    I donĺt test any WiFi with the AO version. Again, Iĺm not going to recommend it to anyone. If you want to play with it, and it sounds better to you, then great.
