Any news on when this might be implemented?

How to manage the live studio broadcasting / airtime and analog line input
Both of the radio stations I work for use Airtime for playout of pre-recorded content, but then route the hardware audio output through a broadcast desk and use a separate streaming client. One radio station uses Nicecast, the other uses darkice. We…

Can't schedule a show to be recorded and rebroadcast
I've just purged Airtime 2.5.1 from a backup machine and reinstalled it. The problem exists in the new install too.

For anyone else having the same problem, Albert said it is a soundcard issue which is currently unresolvable: https://dev.sourcefabric.org/browse/CC-5909

I've just checked our hardware clock and the system clock and they are still the same. I've just changed the timezone to UTC and set the clocks again in case this helps. However we are currently 7 minutes behind in our broadcast! ~$ sud…

Also, after this the 18:30 show was played at 8pm, then repeated immediately afterwards at 10pm! Needless to say this was not in the calendar!

Thanks for the replies. I've never seen a problem with the system clock, but I have just run the following commands: $ sudo dpkg-reconfigure tzdata Current default time zone: 'Europe/London' Local time is now: Tue Aug 19 15:46:…

How to set default colour for recorded and pre-recorded shows
Thanks for the pointer on this John. For any others interested, this is my script: #!/bin/sh set -e set -u # Set these environmental variables to override them, # but they have safe defaults. export PGHOST=localhost #export PGPORT=${PGPORT-5432} …

I tried OSS but unfortunately our production machine isn't configured for OSS. This is becoming more of a problem as we haven't had a live show for a couple of weeks and the playout is now off by nearly 6 minutes!!! See the attached scree…

How to set default colour for recorded and pre-recorded shows
Thanks John for the script - looks like something like this might work for us. Ideally we would cross reference the cc_show_instance table with the cc_show table to only alter those shows that are either marked 'record' or 'rebroadcas…

Tunneling Airtime over ssh
Our production server is running on port 80 so I can't use that port. I can't open another port as it's a managed network. I have ssh access to both the production machine and the backup/testing machine and I used to access the Airtim…

No. Actually there are no streams output from this server. Hardware only.

Hi Roger, thanks for the reply. No we are still having this issue unfortunately. Our system is Ubuntu 12.04.4 LTS (GNU/Linux 3.5.0-51-generic x86_64). I didn't carry out this installation of Airtime so I don't know exactly how it was inst…

Record/Rebroadcast Randomly not working
@Marcin, as I understand it the issue with ecasound is that you cannot have 2 instances running at the same time? This seems to work fine for me on our Ubuntu 12.04.2 LTS server. I have no /etc/asound.conf or ~/.asoundrc but can still run 2 or more …

Record/Rebroadcast Randomly not working
I've just come across the bug preventing the deletion of shows from the schedule. Is there a fix for this yet? We had 2 shows set to be recorded back to back with the same name and neither could be deleted from the schedule. The error thrown by…

Airtime 2.1.2: Uploaded MP3 file appears to be corrupted and will not be added to media library
Yesterday we had a show recorded by airtime 2.1.2 that was not imported as "This file appears to be corrupted and will not be added to media library." I can't find it in /var/tmp/airtime/show-recorder/ or /srv/airtime/stor/probem_file…

Yes we've also had a problem with the stream going silent after some time. We're using airtime 2.1.2 on Ubuntu Desktop 12.04. I checked the stream at 18:43 GMT and it was silent so I ran: sudo service airtime-playout restart and then the…

Airtime 2.1.2 hotfix patch out now
I updated from 2.1.0 to 2.1.2 and now I can't add any shows to the calendar. The add show box just goes grey - see attached screenshot. Nevermind, I think I missed out this step: sudo -u postgres dropdb airtime

2.1.0 showing ON AIR and stream connected when there is no stream connected..
I've been using Nicecast, BUTT and darkice to connect to a master stream mountpoint called live at port 8001. It connects fine, but when I disconnect the source still appears to be available in the web browser.

Airtime 2.1.0 RC2
Just installed Airtime 2.1.0-rc2 on an Ubuntu 12.04 Desktop Virtual Machine and the recorded shows are imported without a name, just a date, ie: 2012-05-31-08:35:00-256kbps Also I'm not sure the automatic upload to Soundcloud is getting throu…
