[RDD] Fixing ALSA playback on weird cards
I sent this earlier to rivendell-prog but never got a reply. Perhaps it was the holidays, or maybe that mailing list is deprecated? -- Forwarded message -- From: Karl Koscher Date: Wed, Dec 25, 2013 at 2:11 AM Subject: Fixing ALSA playback on weird cards To: rivendell-p...@lists.rivendellaudio.org For whatever reason, one of our ALSA playback cards reports a sampling rate of 44099 instead of the usual 44100. Any playback on this device quickly gets distorted, and though some debugging, I found that a byte was being dropped. The culprit is the code in FillAlsaOutputStream that adjusts the amount of data it reads in if the card's playback rate is not the same as the stream's. The amount of data to read is divided by the ratio between the card's playback rate and the stream's rate. If the playback ringbuffer is empty, this increases the amount of data to read beyond the capacity of the ringbuffer. In that case, the ringbuffer code takes the first 2^18-1 bytes, which causes the samples to become misaligned. I'm trying to figure out the purpose of this code. FillAlsaOutputStream will always fill the ringbuffer, so the rate that it's filled doesn't need to be adjusted. It could also be to do a form of poor resampling by dropping samples periodically, but this only works if the playback rate is lower than the stream's sample rate, and it doesn't do this resampling when the ringbuffer is initially filled. Is there a reason for this code, or can it be pulled out? ___ Rivendell-dev mailing list Rivendell-dev@lists.rivendellaudio.org http://caspian.paravelsystems.com/mailman/listinfo/rivendell-dev
Re: [RDD] nothing scheduling
Hello Chris, I ran into this problem a few weeks ago. Rivendell had set a "-" in the "log template name" (http://thebrettblog.files.wordpress.com/2009/12/riv8.png), causing an empty log. Replace the "-" with a "_" (or just remove it) and your problem *should* be solved. Good luck! Peter.

I downloaded and installed the Rivendell Appliance. I have been following the "How to schedule music" blog posting at thebrettblog.wordpress.com but with little success. I have set up my own service and loaded audio carts into my own groups. I've been through the steps multiple times to make sure my host is in the host lists and my service is selected. But I am unable to get the scheduler to schedule anything. The list of events in my clock says they are scheduled events. But when I create a log the events are empty.

[RDD] RML Question?
Has anyone ever tried to use the SO (Serial Out) command in RML? The SO requires the before the command string. Is this asking for the com1, or S0 or /dev/ttyS0? I am having no luck making the SO command work so it would be helpful to know what RML is asking for. ___ Rivendell-dev mailing list Rivendell-dev@lists.rivendellaudio.org http://caspian.paravelsystems.com/mailman/listinfo/rivendell-dev
