It's good to note that the current pcm_share plugin that exists does not allow mixing audio from multiple source channels to one output channel. Instead it can be used to allow multiple clients to access different channels of one PCM device at the same time. For instance you could have share1, which outputs to hw:0 channels 1 and 2, and share2 which outputs to hw:0 channels 3 and 4. What is missing is a pcm_mix plugin, which allows multiple clients to write to the same channels (like esd, arts and other audio daemons). Another currently available option is to use the pcm_shm plugin which outputs audio to a separate aserver process (see alsa-lib/aserver). This plugin does work, but like pcm_share, hasn't been widely used yet. But it's the only working ALSA alternative for concurrent pcm access at the moment. -- http://www.eca.cx Audio software for Linux! _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
