[Jack-Devel] Pull Request: Toggle between run and stop state

by holger＠dehnhardt.org

Dear developers, some weeks ago I added a pull request on GitHub to jackaudio/tools. (A small change on transport.c to implement the toggle command which toggles between top and run state). Is this the right way to submit patches or should I send a patch to this list? Holger

[Jack-Devel] Thread realtime priority

by Yuri

jackd on FreeBSD calls pthread_setschedparam(thread, SCHED_FIFO, &rtparam) with rtparam.sched_priority = 10. I am wondering where does 10 come from? The range for SCHED_FIFO is 0 .. 31, as returned by sched_get_priority_min() and sched_get_priority_max(). The value 10 seems wrong, since the fastest priority is 0, the slowest is 31. In controlapi.c sched_get_priority_min()/sched_get_priority_max() are called for OpenBSD. For this purpose FreeBSD should be the same. So it should be #ifndef __OpenBSD__ && defined(__FreeBSD__). Another problem is that FreeBSD doesn't allow to set thread priorities for non-root users, but jackd is supposed to run by the regular user. At least that's what libs expect it to be (/tmp/jack-{userid}). I have a suggestion: if the process is run with realtime priority, jackd shouldn't attempt to call pthread_setschedparam at all, because the process realtime priority should be sufficient. This code: struct rtprio rtp; res = rtprio(RTP_LOOKUP, getpid(), &rtp); if (rtp.type != RTP_PRIO_REALTIME) { // call pthread_setschedparam } allows to read priority of the process on FreeBSD. The process can be run with realtime priority with this command: rtprio 0 jackd ... Yuri

[Jack-Devel] Recorded from OSS /dev/dsp sound is too high pitched on FreeBSD

by Yuri

Jack runs on FreeBSD 11 with this command line: jackd -r -doss -r48000 -p1024 -n3 -w16 --capture /dev/dsp6 --playback /dev/dsp2 Sound recorded with this command 'jack_rec -f x.wav system:capture_1' is too high pitched compared to the original. Recording using the 'sweep' app produces the correct pitch. What is wrong? How to fix? jack-0.124.1 installed from the FreeBSD port. Yuri

[Jack-Devel] Suggestion to include loopback capability in a Jack session

by Thomas Howe

Hi Jack-devel, This time it's not an impossible-to-reproduce bug, but a feature request! Let me know it there's a better place to post this. I think similar things have been suggested before, but this idea for a 'loopback' client hasn't as far as I'm aware. A loopback Jack client to intercept streams to and from partially Jack-aware programs such as SMPlayer and Firefox would be useful. Both of these programs output audio to Jack, but only to the system ports, which makes routing the audio inconvinient. My setup includes a Jack client for pre-speaker processing (called "Apps Out"), which reduces the audio by 35 dB and applies EQing, so any unexpected connetions directly to the system ports are inconveniently loud and muddy. Even if these programs gain support for changing their default output ports, there may be other programs that won't. The ALSA loopback device effectively pretends to be hardware, so most ALSA-aware programs will be connected by default to Apps Out (and its counterpart "Apps In"), as there is a persistent connection between these clients and the ALSA-Jack bridge. Some way of configuring a Jack session so that programs would think that Jack's hypothetical loopback client is the system capture/plackback - with the real system capture/playback appearing to be a non-system client - would solve everything. Like adding a monitor strip for use between the apps and the hardware. Failing that, is there a way I can force partially Jack-aware programs to use the ALSA loopback device instead of Jack, maybe by hiding Jack's existence? - Tom
