My alsa is 1.0.14 but I'm using the 'HG' version of the alsa-drivers and alsa-kernel packages so that basically gets me the latest-and-greatest drivers from the source repository if I understand correctly. I saw some patches coming by in February and they are already in there so I presume I'm working with the most current source.
I'm intrigued by the asound.conf, is there any specific configuration you needed to make the aloop device work properly? I'm using the distro-configured alsa (ubuntu 7.10) and there is no such file somehwere in /etc. Even on my debian server (running Etch), I can't find it.
Kind regards, Benjamin
I tryied to use the HG versions, but they didn't work well for me. Maybe you should give the 1.0.16 a try, just to make sure. I need an asound.conf since my network application uses a very low latency, that is not default. I am attaching my asound.conf. Another possible source of problems are the artsd and esd daemons, are they running?
Hope that helps.

Hi Gustavo,
I just downloaded the 10.0.16 version and the code for aloop-kernel.c looked quite different from the one in the HG version. I was under the understanding that the HG version is a current development snapshot that eventually gets tagged into an official 1.0.1xx version. That's not the case then?
Anyway, I will try with the 10.0.16 version, I see some stuff about a #define called SND_CARD_LOOPBACK_START_SYNC, that sounds promising perhaps. I've also looked at the config file you attached, the stuff about period_time and buffer_size also looks quite interesting and is perhaps something I should play with then :)
I'll let you know how things work out! Thanks for your continued help, it is greatly appreciated...
UPDATE: I built the 10.0.16 version of snd-aloop and it seems to perform a bit better out of the box! I will experiment a bit more...
Kind regards, Benjamin
