Re: [PLUG] Need Assist with Audio on CentOs 6.6
Sorry I haven't gotten back to you yet, busy week! If icecast would work for you, that seems like a nice tutorial! If you are sticking with your solution using jack, the dbus thing I mentioned earlier isn't a big deal, it just makes for little smoother setup. Turn off that Dbus option in qjackctl, set your sample rate (44100 is a good default), Frames/Period Periods/Buffer(start high, work lower once youve got a functioning setup), Then hit the start button on the main qjackctl window. If no red numbers appear on the right of the little display window (xruns), your settings are good! Without dbus, make sure of 2 things, 1) that jack is started before any of your audio programs that rely on jack, and 2) the audio programs are closed before starting jack. After its started and seems free of xruns, open up vlc or something, go to the audio settings and tell it to use jack. Then play a song or movie and see if youre getting sound. If so, look at the Connect window in qjackctl and expand the entries to see how everything is connected together. Let me know if any of these steps don't work out and good luck with either solution!

Re: [PLUG] Need Assist with Audio on CentOs 6.6
Thanks Kyle, I would like to pursue this with your suggestions. The day (editing) job is taking my project time today, but soon as I have time I'd like to get my current status documented for you first, so I'm not flailing around in unnecessary territory. Will be back then. I appreciate your help with a place to start. -Steve On 8/3/2015 9:03 PM, Kyle Kneitinger wrote: Hi Steve!

[PLUG] Need Assist with Audio on CentOs 6.6
Hello, Just joined the group today for some guidance on my internet radio project. If there are pro audio folks currently streaming to the net via Jack - processing (stereo_tool) - shoutcast stream server, I am looking for tutorials or previous solutions to a specific problem with this procedure. Google only goes so far, and so far not addressing this need. This is apparently a trivial matter in the debian world. I'm using a free CentOs distro supposedly designed for this purpose, but Jack's not cooperating (among other things). As you may have gathered, I'm new enough to linux to be dangerous but willing to learn Many thanks for any insight.

You can find out if you have the dbus version of jack installed if the jack_control command exists in the terminal. - If latency is not a huge issue, higher buffer sizes are more reliable and use less cpu. Starts with very conservative settings, and increase bitrate and decrease buffer size from there if you want lower latencies and higher quality. - If that red number appears in the qjackctl display, that means you have an xrun, or dropped sample. This is usually indicative of settings too intense for your hardware. I've spent a great deal of time loathing JACK, until working through it and now loving JACK. It is a bit finicky, but it is a fantastic piece of software once it is configured. Let me know anything I can help you with! - Kyle Kneitinger On Mon, Aug 3, 2015 at 8:28 AM, Steve Atkins fsra...@comcast.net wrote: Hello, Just joined the group today for some guidance on my internet radio project.
