Re: [Jack-Devel] How does --hwmix work?

IIUC HWMIX is a feature to use a sound card without a sound server, but since jack is a sound server, this option might be irrelevant. I might be mistaken ;). However, if you want a hardware mixer, you don't need a jack option, instead try running hdspmixer . I suspect hdspmixer doesn't work with all RME cards. Regards, Ralf [1] [rocketmouse@archlinux ~]$ man jackd | grep hwmix -A3 [rocketmouse@archlinux ~]$ man jackd | grep hwmon -A3 -H, --hwmon Enable hardware monitoring of capture ports. This is a method for obtaining "zero latency" mon‐ itoring of audio input. It requires support in hardware and from the underlying ALSA device driver. -- (M-Audio Delta series, Terratec, and others) support --hwmon. In the future, some consumer cards may also be supported by modifying their mixer settings. Without --hwmon, port monitoring requires JACK to read audio into system memory, then copy it back out to the hardware again, imposing the basic JACK system latency determined by the --period and --nperiods parameters. -- "Access to all language versions of Wikipedia was blocked in Turkey on 29 April 2017." - https://en.wikipedia.org/wiki/Government_censorship_of_Wikipedia#Turkey
