Depends on software. ESD (and now pulseaudio) support multiple simultaneous inputs to a single output. So I can play 2 sound tracks at once (cool! Pink Floyd and Bach at the same time). The frontend tool, ESD or pulse, combine the data to make a single output stream.<br>
<br>On the output side, the process is single threaded. It would be very difficult to share the hardware device with multiple threads.<br><br><div class="gmail_quote">2008/6/21 Marc Ferguson <<a href="mailto:marcferguson@gmail.com">marcferguson@gmail.com</a>>:<br>

Hi all,<br>
<br>
Based on my observation it seems that the sound for my linux box is single threaded. If one device uses sound, it seems to lock it and if another application tries to use it, it is pretty much unsuccessful. Is this true or do I not have the right drivers installed. Here's my setup:<br>
<br>
Vendor: ATI Technologies Inc<br>
Model: SBx00 Azalia<br>
Module: snd-hda-intel<br>
<br>
PCM Device: ALC883 Analog<br>
<br>
ALSA Driver version: Driver Version 1.0.16rc2<br>
ALSA Lib package(s): alsa-lib-1.0.16-3.fc8<br>
ALSA Utils package(s): alsa-utils-1.0.16-3.fc8<br>
<br>
I'm running Fedora 8. Thanks for the clarification.
