Pulse by default now will create the same number of channels as well. For a 10 channel card this is over doing things. Most uses of bridging pulse to jack only require 2 channels (or even 1 for phone work). Jack just calls channels 1, 2 ... to whatever. Pulse names them for surround up to 7.1 and then calls any extra aux1 etc. I do not know if pulse also plays with the sound to add surround stuff or not. I have had one user tell me it does... but I don't know. Personally, I would like to see the jack source/sink treated as a device. If the jack detect module is loaded then a device appears for it weather jack is running or not. It should allow jack to be set up in the same way as a card, stereo, 5.1, 7.1. Input or output only etc. Then if jack does show up that many lines are created. It really doesn't matter if the device jack is talking to has more or even less channels than pulse sets up. -- Len Ovens www.OvenWerks.net ------------------------------ Message: 14 Date: Tue, 26 Feb 2013 18:22:42 -0700 From: Bearcat M. ??ndor <hometheater(a)feline-soul.com> To: linux-audio-user(a)lists.linuxaudio.org Subject: Re: [LAU] Jack users - how many channels do you want with PA module-jackdbus-detect?
