Notes to self... (fighting a Rivendell install in an Ubuntu VM, and connecting it to a Rivendell "Broadcast Appliance")

...just because it's been forever and a day since I've posted anything, here's a little something I've been fooling with at home. The notes are a mess, and might only make sense to me; actually, there's a pretty good chance that they might not even make much sense to me, anymore.

Anyway, the gist--before you dig any deeper and get royally confused--is that I was fighting with trying to create a virtual machine on my bedroom PC in order to connect to my "streaming" PC downstairs, and go through some of the same headaches that someone at a radio station might experience on a routine basis. An actual post on all this stuff might show up in the future--and by "actual post" I mean something that took some time to write, instead of an ol' copy-paste of notes.

...oh, the deal with the notes? Yeah, well, I had to crash my attempts a couple times, and got frustrated with trying to retrace my steps from memory. So, yeah. Notes! Plus, I figured I wanted to eventually come up with some sort of howto at a later date, as the Rivendell documentation--what documentation that exists--is a bit confusing. Oh, and JACK documentation, too.

Unfortunately, these notes kind of drop off toward the end, as I finally began to have success... installed ubuntu 14.04--made sure to set a "real" hostname, as Rivendell will expect/work-a-helluvah-lot-better-with one reboot

installed guest additions changed ip to manual -- Rivendell will expect/work-a-helluvah-lot-better-with manual IP... plus, I connect so many devices, I like handling IPs instead of relying upon DHCP installed gnome-session-fallback gdm - made gdm default logout, back in to get responsive session

enabled other canonical sources, refreshed began instructions at https://help.ubuntu.com/community/UbuntuStudioPreparation[1] changed terminal to unlimited scrolling saved suggested packages from first studio prep step... would not install--may check later if packages would be worthy tracking down--moved to kxstudio repo step installed kxstudio repo installed low-latency kernel skipped wine, etc. why need wine, since running in VM? did update step, and reboot.

logged in via gdm. saved machine state, thus far.

sudo apt-get install pulseaudio-module-jack sudo apt-get install qjackctl ...installed the following suggested from the studio guide--eh, why not? look promising: sudo apt-get install vlc vlc-plugin-jack audacious asunder soundconverter patchage

ran qjackctl to configure JACK ...left all defaults. started server via start 'play' button ...messages window showed a few errors. ...stopped jack dbus error. dammit. ...killed qjackctl started qjackctl, changed dbus option to off, exit qjackctl killed jackdbus from sysmon started qjackctl and server... tons of errors, it stopped jack. sudo adduser username audio start again. still borked. ...restart

error seems to be with trying to use dbus and sink module... ...managed to start/stop jack twice with dbus disabled.

...after a ton of tinkering, finally discovered a solution that is working ...have no idea of the steps i used, now. @#$%! ...did have to create .asoundrc in ~/ ...am running via dbus interface again ...wish i could figure out what happened to make things work. ...created save point.

proceeded to rivendell part... *in order to install qt3 dependency per instruction page, did this: echo "deb http://archive.ubuntu.com/ubuntu[2] precise main universe multiverse" | sudo tee /etc/apt/sources.list.d/precise.list **sudo apt-get update sudo apt-get install libcdparanoia-dev libflac++-dev libsamplerate0-dev libid3tag0-dev libid3-3.8.3-dev libcurl4-gnutls-dev libsndfile-dev qt3-dev-tools libpam0g-dev libsoundtouch1-dev libasound2-dev libtwolame-dev libmad0-dev libjack-jackd2-dev libqt3-mt-mysql build-essential sudo apt-get install libmp3lame-dev polymer qt3-qtconfig mysql-client wget https://software.paravelsystems.com/source/rivendell/rivendell-2.13.0.tar.gz[3] tar -zxvf ~/rivendell-2.13.0.tar.gz cd ~/rivendell-2.13.0 ./configure make

computer restarted. had to delete, untar, configure, make again. make install ***note--for both runs of configure, did not configure to set rd-bin directory. had an issue in a previous attempt with this. ...skipped the copying of pixmaps, etc. sudo addgroup rivendell sudo adduser whoami rivendell sudo gedit ~/rivendell-2.13.0/conf/rd.conf-sample ...changed audioowner ...changed hostname to server IP ...changed syslog to file ...changed log file paths ...saved as /etc/rd.conf skipped apache conf sudo mkdir /var/snd sudo chown whoami:rivendell /var/snd sudo chmod 0775 /var/snd skipped ugly fonts qtconfig -- changed to guide recommended to make it pretty :-)

mkdir /home/jeremiah/rdlogs mkdir /home/jeremiah/scripts sudo cp /etc/init.d/rivendell ~/scripts/rivendell-init-backup ...I wanna see if i can modify the script later... sudo cp /etc/X11/xinit/xinitrc.d/start-rdmonitor.sh ~/scripts/start-rdmonitor.sh.backup sudo rm /etc/X11/xinit/xinitrc.d/start-rdmonitor.sh save, restart

!/bin/bash #FILE: jack-after-startup.sh

Start Rivendell Daemons /usr/local/bin/caed /usr/local/bin/ripcd /usr/local/bin/rdcatchd sleep 5 #not strictly necessary

!/bin/bash #FILE: jack-on-shutdown.sh

Stop Rivendell Daemons killall rdcatchd ripcd caed sleep 5

created above files, made executable, added to qjackctl created simple patchbay for rivendell_0 playout_0L,R to system playback_1,2

...beginning the networking part--part riv, part my stuff ...riv nfs based stuff from https://tecwhisperer.com/install-rivendell-radio-automation-part-3-install-client/[4] sudo apt-get install cifs-utils nfs-common ...followed autonfs instructs ...noticed goofup in copying code. fixed. (copy did not keep formatting, plus html char$ came through) restarted script/job ...after files populated, noticed wouldn't play due to differing UID and GID. before tweaking server's export options--which were set to root for share, restarted VM

jack started freaking out again, and sound from pulse started coming at the wrong rate. :-/ performed dist-upgrade, restarted guest and host. ...had to re-install vbox additions due to dist-upgrade; restart again.

looked at rivendell script, noticed it really wasn't calling anything that relied upon original location, so moved to /usr/local/bin. still requires sudo to run. will figure this out later, by adding to sudoers

having too many issues with jack. going for jack 1, now, instead of jack 2. this removed qjackctl. :-/ attempted to work with jack using cadence. worked for a while. still having issues. going to try and kill pulse altogether, and use jack+alsa like the machine downstairs. :-/ edited /etc/pulse/client.conf--autospawn=no ...did this because total removal of pulse starts killing ubuntu. reinstalling jackd2 and qjackctl, then restarting.

after trying to figure out the issue with the sample rate for the card, finally discovered an answer: https://www.withoutthesarcasm.com/fixing-audio-in-linux-guests-virtualbox/[5] ...crap. maybe. jack still failed. going back to jack 1, and trying to compile qjackctl, as ubuntu keeps trying to force jack 2 if i install qjack using 0.4.2 from sourceforge, extracted to home. discovered need of following packages and symlink through configure and make attempts: sudo apt-get install libjack-dev qt5base-dev sudo apt-get install libqt5x11extras5-dev System Settings) Noticed that if daemons haven't already been called, rd apps will call for startup and initialization of daemons on their own.

"modprobe snd-aloop" added to /etc/rc.local -- there's gotta be a better/different way, but i'm still learning linux as i go

edited sudoers to allow nopasswd on rivendell "daemons" for my user and the rivendell group
