Re: [LAU] a NEW question about pitch and speed

Just a random thought: in ALSAmixer, if they exist, check the values of 'Multi Track Rate Locking' and 'Multi Track Rate Reset' . Both should be off. 'M' for mute will turn them off and on. These settings seem "sticky" so you'll need to unload/reload the drivers, or reboot, in order for then to take effect. [[ if any alsa expert has opinions on what these settings are for -- other than causing massive, inexplicable hard-to-debug problems with soundcards and/or causing Jackd to lockup when they're set... ]] Much more rarely, I've also seen problems w/ "ondemand" scheduling (CPU clock changes) versus "performance" (steady clock at top speed). for example, on a dual processor machine, as root, try: /usr/bin/cpufreq-selector -c 0 -g performance ; /usr/bin/cpufreq-selector -c 1 -g performance For example, if you use the program 'mixxx' and output to ALSA directly, running in "ondemand" mode causes it to lock up. Running it through jack allows it to work in either ondemand or performance mode. Niels http://nielsmayer.com
