Hello, all, I'm having problems with pulseaudio on my Ubuntu 18.04 system, and I think I've narrowed it down to pulseaudio not starting correctly on system reboots. After I reboot my system, I have no input or output devices shown in the sound control panel, and can't hear anything. I can see pulseaudio running, however: $ ps aux | grep pulse gdm 1832 0.0 0.0 1121148 16396 ? Ssl 14:31 0:00 /usr/bin/pulseaudio --daemonize=no $ I can't kill it: $ pulseaudio --kill E: [pulseaudio] main.c: Failed to kill daemon: No such process $ ps aux | grep pulse gdm 1832 0.0 0.0 1121148 16396 ? Ssl 14:31 0:00 /usr/bin/pulseaudio --daemonize=no $ sudo pulseaudio --kill E: [pulseaudio] core-util.c: Home directory not accessible: Permission denied E: [pulseaudio] main.c: Failed to kill daemon: No such file or directory $ I get these messages in /var/log/syslog when I reboot: Sep 27 14:26:30 kevin-desktop org.gnome.Shell.desktop[2108]: ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Connection refused Sep 27 14:26:30 kevin-desktop org.gnome.Shell.desktop[2108]: ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Connection refused Sep 27 14:26:31 kevin-desktop systemd[1703]: pulseaudio.service: Main process exited, code=killed, status=9/KILL Sep 27 14:26:31 kevin-desktop systemd[1703]: pulseaudio.service: Failed with result 'signal'.

Sep 27 14:26:32 kevin-desktop systemd[1703]: pulseaudio.service: Scheduled restart job, restart counter is at 1. Sep 27 14:26:32 kevin-desktop pulseaudio[4004]: W: [pulseaudio] pid.c: Stale PID file, overwriting. However, if I manually start it, I get two copies. I also get all my input and output devices back in the sound control panel. $ pulseaudio --start $ ps aux | grep pulse gdm 1832 0.0 0.0 1121148 16396 ? Ssl 14:31 0:00 /usr/bin/pulseaudio --daemonize=no kevin 3901 2.7 0.0 1457716 16752 ? S<l 15:30 0:00 pulseaudio --start $ And, sound works again, although with some oddities. I can hear the 'pock' when I adjust the volume with the sound control panel, but not with the volume control in the upper right of my desktop. And, the sound control panel Test Speakers don't work, they don't even change visually from 'Test' to 'Stop' like they used to. Any ideas on how to fix this? I've really thrashed the sound system on my workstation, trying to play MIDI sounds through Zoom and other tasks. I've added a lot of sound software, like Cadence, but then thought I removed it all because it wasn't working. I reinstalled pulse-base and alsa, but this didn't work. Thanks for any suggestions or advice. -Kevin

Problem with input/output of the RME Fireface 802 sound card in Ubuntu Studio 20.04 with Jack

by Sebastian Roth

Hello everyone, I am new to this list and also new to Linux. But need Linux to play a virtual acoustic scene for studies with hearing aid users. First, about my setup. I have an RME Fireface 802 sound card that should drive 12 speakers in a speaker circuit. I use Ubuntu Studio 20.04 LTS as operating system and realize the routing via JACK. The Fireface is connected to the computer via USB and runs in ClassCompliant mode, because RME does not provide drivers for Linux. According to RME the ClassCompliant mode should allow in- and output of all channels also with Linux. The soundcard is recognized and I can also use 8 output channels for playback. But I need all 12 output channels including the two headphone outputs. JACK recognizes 22 channels or shows them in the graphical user interface. But the outputs 1 and 2 of the Fireface do not provide playback and no input is recognized. Does anyone have experience with the Fireface 802 in Linux or had a similar problem with an RME soundcard and can help me? Thanks for any feedback! Best regards, Sebastian

[semi-OT] acoustic Instrument question

by Jeanette C.

Hey hey, I'm looking for the name to an instrument. I had a feeling I was looking for a whirly tube (or corrugaphone), but apparently not. I'm looking for the sound in this song: https://www.youtube.com/watch?v=m-jYpFa3Ppk audible between 22-27 seconds. It sounds like a whispering diggeridoo or jaw harp. I thought a corrugated tube could produce this sound when whilred, but all demos I heard of this were much higher and much more pronounced in clear pitch. I'd be very grateful if someone could give me a clue or pointer of how to continue the search at least.

[music] Real love

by Jeanette C.

Hey hey, my latest track "real love" is inspired by Simon Collins' solo debut (All of who you are" and is probably an indie/electro pop ballad: https://youtu.be/xkDbP3DHL_U Direct OGG download: https://www.dropbox.com/s/cv0ipr2o1f7fx5d/real_love.ogg It was said that this might be my best production yet, even with me spoiling the song by singing. :) On the Linux side I used LinuxSampler with several free and commercial libraries and the usual production and recording software. Special credit should go to the TAP chorus, which is beautiful! Lyrics follow below. Best wishes, Jeanette *** Lyrics for "Real love" *** [Verse] Many a time - far at sea - you are my lifeline With just the smile in your voice. When events bare me down until I'm supine, I feel your call and I have no choice But to shoulder the weight of the world like a cloud... Thus in fade I rejoice With my feet on the ground and my heart reaching out... - Patiently listening to the lonely, Solitude melts in your spell. With wide open arms you never knowingly Coax me like pearl from a shell. The turmoil you cause, you will sooth with a laugh Towards the storm... Then you summon the light and the blue black above is torn... [PreChorus] Hell is on fire Heaven's burning bright. 'Cause now I aspire To ask if you requite [Chorus] My love (all my love) To live outside a dream on safer ground In your love (all your love) To face our days And make our ways Hand in open hand... [Verse] Compassion alone shall bestow your noble birthright, And thus give credence to you. My princess, hold court with the timid and the forthright! Joy will provide all that is due. And together we serve with the creatures of earth Where we stay. And in kisses we share what a passion is worth Day to day. [Prechorus] [Chorus] [Instrumental] [Chorus] *** End of lyrics *** -- * Website: http://juliencoder.de - for summer is a state of sound * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * Audiobombs: https://www.audiobombs.com/users/jeanette_c * GitHub: https://github.com/jeanette-c Don't, don't let me be the last to know Don't hold back, just let it go <3 (Britney Spears)

live with keyboard

by Gerhard Wolfstieg

Hello dear readers, I wish to find the best way to play live on a MIDI keyboard with softsynths and plugins in my linux notebook (avlinux or debian – or another if someone knows a better one for this purpose) with a good USB audio interface (komplete audio 6, which is running very well with jack1 (possibly changing to jack2)) Mostly I have to be able to switch between preconfigured sets of sounds quickest and easy. The topic is boundless. Therefore I ask you for some orientation. Grüße, Gerhard

New Music

by Will Godfrey

Over in KVR I used to be a regular contributor to the Music Cafe Contest, but that has really thinned out as other things got in the way. However after more than a year, I've finally managed to come up with something new again, and thought folks here might be interested in how I went about it. The track is named Pensive and is downloadable from Kara Moon here: http://www.kara-moon.com/forum/index.php?action=dlattach;topic=8697.0;attac… Anyway, here goes. It's all Yoshimi, of course. I started out with an improvisation across two keyboards feeding into Rosegarden on tracks 1 and 2. From there, as well as recording MIDI, it passed on to Yoshimi. In the past, I would have run with a single keyboard with Yoshimi set up as a split keyboard, but that's much less comfortable and not improv friendly. With the melody and backing laid down, I then spent some time with minor edits, and a range of voicing selections, ending up with 'Solo' for the melody, and 'Multi-Rushes' for the backing. Multi-Rushes has a lot of 'movement' built in, but I went further with it, and MIDI learned both filter Q and filter CutOff to the MOD wheel, setting a block on it acting as normal. I then set the control range to run between 50% and 75% for a more subtle effect, and recorded this as MOD wheel to Rosegarden, operating the control to get the swells as and when I wanted them. For the bass, I then directed one of the keyboards to channel 3 and played along to the rest. I actually set this an octave high for the recording - it's much easer to be sure you're hitting the right notes! The patch is 'Simple Bass' After that, it was just a matter of dropping the bass an octave, and a few cleanups before making an audio recording. I hope you like the result. -- Will J Godfrey https://willgodfrey.bandcamp.com/ http://yoshimi.github.io Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.

[music] Just one more time

by Jeanette C.

Hey hey, ... it's neither a Flower King's nor a Britney Spears cover. It's a cross between 90s rave and 10s Martin Garrix clubbing sound. With a healthy dose of Yoshimi for plucks, pluck layers and the diamond lead. Apart from that, it's more analogue electronics and some wavetable synthesis doing their thing. The vocoder and boom are created in Csound. https://youtu.be/E_Tz4X4_Ev4 and direct OGG: https://www.dropbox.com/s/3dw07w28wrd4a25/just_one_more_time.ogg Best wishes and enjoy, Jeanette -- * Website: http://juliencoder.de - for summer is a state of sound * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * Audiobombs: https://www.audiobombs.com/users/jeanette_c * GitHub: https://github.com/jeanette-c Ain't no way I'll be lonely <3 (Britney Spears)

Packet-In Spaceman is gone, plans to restore it?

by hollundertee＠gmx.net

Hi there, I was somehow very fond of that album in particular but it seems it has entirely vanished of the web by now. I could find the wiki page and rpm08 page on archive.org but no music. I was just wondering whether anyone cares to restore it in some fashion. I have the rpm08, 09 and 12 final mix but no project files or anything like that. Regards, Philipp
