Of course I understand that you can play several streams at the same time (without using a sound daemon like esd/arts/etc). But is hardware mixing much better than software mixing (I think one must use dmix for software mixing)? This is also an important question for me to decide which soundcard I should buy. In an additional post to this list I told that I'd prefer the TerraTec Aureon 7.1 Universe. But this one porbably doesn't support true hardware mixing and true full duplex (does it?). So if I buy an expensive soundcard like this (it costs about € 150,00) should the card have the hardware mixing feature? What my card should be able to do is (of course with all additional features like 7.1 sound and so on)... - esound (or any other sound daemon) should be able to access the card so that GNOME applications that use esd can play sounds or record audio - but in each case it should be possible for other processes to access the ALSA devices too (both playing and recording); like mplayer,.. or gstreamer applications if I set up gst to use ALSA). - and I want Ekiga (gnomemeeting, or any other VoIP software to be able to open conferences (multiple conferences too, although I think Ekiga itself does not support this yet) - which means Ekiga must be able to play and record audio (via ALSA but not ESD) - AND !! while doing this (communication via VoIP) I still want to hear my other system sounds (those from GNOME via esd or other ALSA using applications. Ok,.. so of course full duplex is required for all the above (otherwise I would not be able to record and hear simultaneously). But is hardware mixing required for this? If so,.. can all this achieved (without any drawbacks to the hardware mixing way !!!) via software mixing? I've already did some poor tests with software mixing (as I told before I'm not an ALSA expert ;) )... but the sound came always very disturbed or with a big lag. Are there applications that can excusively lock the ALSA devices (for playing and/or recording) even when hardware and/or software mixing is set up? (I ask because I wonder wheter applications like Ekiga do this) > What's your libasound2 version? Dmix should be enabled automatically > for this chipset.

Ok,.. I'll do that,.. but please not that this problem exists since last october (when I assembled the computer). I've just been to lazy to take care on it until now ;) Regards, Chris. ------------------------------------------------------- Using Tomcat but need to do more?
