The issues Zenaan does experience are likely related to jackd, a sound server that cares about sample accuracy [1]. When using jackd, CPU frequency scaling does matter a lot! If you don't believe a professional audio engineer using Linux audio since around 10 years, perhaps a Linux audio link is able to enlighten you. "CPU frequency scaling daemons that scale the frequency of the CPU depending on the CPU load could cause xruns in some cases. More recent versions of Jack1 (>= 0.118.0) are suffering less from xruns or run xrun free with a CPU frequency scaling daemon enabled that's set to a scaling governor like ondemand. A specialized CPU scaling daemon is in the works that depends on the DSP-load instead of the CPU load: jackfreqd" - http://wiki.linuxaudio.org/wiki/system_configuration [1] -------- Forwarded Message -------- From: Ralf Mardorf <ralf.mard...@alice-dsl.net> To: debian-user@lists.debian.org Subject: Re: going mad - starting jackd starts pulseaudio Date: Fri, 10 Jan 2014 09:35:19 +0100 Mailer: Evolution 3.10.3 JFTR some users might find setting up jackd to complicated, but jackd provides advantages, e.g. "Within software, jackd provides sample-accurate synchronization between all JACK applications." - http://manual.ardour.org/synchronization/on-clock-and-time/ This does mean, that signals are not out-of-phase, so there won't be unwanted filtering effects. The easiness of other sound servers comes at a price. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
