Re: [Alsa-user] Multiple dmix instances on multiple cards

[EmIScA <em...@em...>]

aoss doesn't work well with skype and vmware because both use mmap 
access and full duplex.
Skype works with aoss only with certain asound.conf settings (with a 
trial & error method), but sometimes the audio gets mute, you can ear 
but not speak etc.
The only interesting solution I've found is oss2jack, but it's dependent 
on jack (you must use jack for each software that uses audio). How could 
be configured the jack plug in asound.conf? I tried the combo (jack + 
oss2jack + alsa jack plug), but I haven't got it to work properly.
I'll wait for new software versions that support natively alsa and 
dmix.. meanwhile I use two separate non mixed soundcards.
