audio/media related reports to bugzilla.redhat.com ignored?
by Niels Mayer 30 Mar '26

30 Mar '26

For audio/media related apps and issues reported on bugzilla.redhat.com , this is the pattern: bugs get filed, they're never acknowledged && totally ignored. Eventually people stop filing bug reports as it ends up being a waste of time and the quality of the distro goes down as result.... https://bugzilla.redhat.com/show_bug.cgi?id=566665 [abrt] instability from snd-mtpav on PCI parallel port, causes crash in jack-audio-connection-kit-0.118.0-1.fc12 (edit) https://bugzilla.redhat.com/show_bug.cgi?id=588965 [abrt] crash in gnome-media-apps-2.28.5-1.fc12: Process /usr/bin/gstreamer-properties was killed by signal 11 (SIGSEGV) (edit) https://bugzilla.redhat.com/show_bug.cgi?id=602900 [abrt] crash in alsa-tools-1.0.22-1.fc12: ____strtol_l_internal: Process /usr/bin/envy24control was killed by signal 11 (SIGSEGV) (edit) https://bugzilla.redhat.com/show_bug.cgi?id=602903 envy24control "Reset Peaks" button nonfunctional; metering shows no peaks Niels http://nielsmayer.com PS: the above is not my experience with non-media related bugs, which are handled quickly and effectively, e.g.: https://bugzilla.redhat.com/show_bug.cgi?id=575875 https://bugzilla.redhat.com/show_bug.cgi?id=445543#c20

Re: [Fedora-music-list] Good hardware specs for a "Fedora Music" box?

I would like to be able to record stuff from guitar, midi-keyboard, microphone, DJ setup (via line input I suppose), and then edit the results with the appropriate applications. Not all at once, but maybe 1-3 inputs at a time. The ability to play in real-time through the computer's output would be very important I think as I reckon it's much harder to work any other way. That's all I can think of right now. I currently have an SB Live with the LiveDrive thing, which has all the inputs I need, but I am thinking in terms of general system horsepower (RAM/CPU/disk etc). Finding a supported sound card it's really a problem, I'll just go with M-Audio for that. But I would like to know if I need to get one to do what I want. K. -- Kev Green, aka Kyrian.

To fully test you'll need a guitar and pickup plugged into your soundcard, but even a go/nogo on whether it starts would be helpful. Where I developed the package, it works OK, but another older AMD machine, it fails during startup. This will help me to decide whether to push it to the F8,F9 updates repos. DaveT.

whysynth doesn't work

I got whysynth-dssi-20060122-7.src.rpm from here: http://people.redhat.com/green/FE/devel/ I rebuilt it on FC6 without problems. The thing is, the GUI doesn't show up. The program appears to be working, I see the outputs being automatically routed in qjackctl, but there's no GUI anywhere! ############################################### $ jack-dssi-host whysynth.so jack-dssi-host: Warning: DSSI path not set jack-dssi-host: Defaulting to "/usr/local/lib/dssi:/usr/lib/dssi:/home/florin/.dssi" jack-dssi-host: OSC URL is: osc.udp://rivendell.home.local:15040/dssi/whysynth/WhySynth/chan00 host: Ready WhySynth_gtk starting (pid 4305)... ############################################### -- Florin Andrei http://florin.myip.org/

Low Latency vs. Real Time Kernel - actual latencies ?
by Be 05 Apr '15

05 Apr '15

Hello Fedora musicians, I've been lurking this list for a little bit and this is my first time chiming in on something. I think it is important to pursue an official realtime kernel for Fedora. I think a distribution focused on audio without a realtime kernel would have a serious bug, that IMO, would be worth delaying publication for. >So I had a beer with hansomepirate(jdulaney), who is, or was on the kernel sig, last night and we got to talking about a RT kernel. > >Last time we talked to the kernel folks about an rt kernel, they weren't impressed with the "need" for Fedora, but that was before the Spin was officially out. > >Now might be a good time to raise this issue again? I dug through my archives and found this thread. Now that we have an actual spin that's out, we can actually redo some of the testing to have more realistic tests. (multitrack with effects) > >I feel like right now, it's one of the few benefits that the ubuntu studio folks have (or at least claim to have) over us.

Need soundcard advice
by William W. Austin 02 Jan '15

02 Jan '15

My wife composes, and for playback she has used an Audigy2 PCI card in her desktop machine for years. That computer is beyond it's last legs now, and her new one has only PCIE slots. (Yes she uses Linux for her composing and playback.) The problem is that she uses the Midi feature of that card and has sound fonts that she loads (about 126 MB in size) into it. She has given up trying to find one and has asked me to help... but so far I've struck out. Are there ANY PCIE sound which is roughly the equivalent of the Audigy 2 cards? I won't say "money is no object", but I'm approaching the point where cost is less important than finding such a card if on exists. Any pointers on this issue will be greatly appreciated. Thanks in advance - Bill -- william w. austin airedad(a)att.net "life is just another phase i'm going through. this time, anyway ..."

Re: [Fedora-music-list] Low Latency vs. Real Time Kernel - actual latencies ?
by Brian Monroe 01 Jan '15

01 Jan '15

I agree that we need lag to be less than 5ms with no xruns for serious musicians. It makes a difference. I was chatting in #opensourcemusicians about the rt patch issue and someone threw this out there: http://www.funtoo.org/Kernel/configs/realtime I'm smart enough to get what they're doing, but not smart enough to know if this is what we're already doing in Fedora or how it'll affect other security concerns. Also the settings listed for /etc/security/limits.conf is setting you up for a bad time. They said they could get less than 1ms with no xruns (except at application startup) which sounds promising. Certainly if we're shooting for less than 5 ms instead of less than 1ms.

Some of the names of the real time kernel developers listed on the PlanetCCRMA kernel-rt page are Red Hat employees. I would like to see Fedora be the premier linux distribution for music. But until we can overcome the concerns listed in the Musician's Guide we will probably not have a real time kernel in the Fedora repositories. Maybe a Fedora "Re-Mix", or Fedora.Next and Workstation with the works with Fedora software library may break the ice. -- Jeff

Carla/Cadence
by The name of my band is 1984 22 Dec '14

22 Dec '14

hi, since lv2rack and zynjacku are currently unmaintained (btw, on my F20 install i'm getting runtime errors on both and do not start), i've started playing around Carla/Cadence packages by falkTX. I had to install indicator-cpufreq-selector and change the policy in polkit file and build many missing packages from source to get Cadence working, but now it seem to be ok. i had to update jack_capture to the lateset version as well, in order to obtain freewheeling rendering. i'm wondering if there is any plan to include these packages in the spin by default cheers max
