So my question: > is it possible to activate ac3-passthrough with the alsa-driver? > as i know spdiff-passthrough is currently not possible with the es1371 and alsa-drivers. i can't verify it cause i have no external iec958 capable device, but some users reported that it doesn't work. the problem is that the current driver configuration is inclompete due to lack of information about the internal iec958-handling, but if you got it to work with the OSS-drivers you probably could improve the alsa-driver too ;). > What software do I need to do it with mplayer? for 'native'-alsa-spdiff-passthrough with mplayer you need no extra software. you have to pass the iec958 capable subdevice to it like mplayer -ao alsa9:hw:0,3 -hwac and you have to switch on the iec958-playback-switch in your mixer (name depends on your soundcard). that would be all, but as i never see (hear) it in action i can't give you any guarantee that it will work. there is a lot of documentation for spdiff configuration included in the mplayer sources, take also a look at DOCS/tech/hwac3.txt. -- regards ____- joy ________/\---------%%%___________----------- webcast every sunday 2000 cest at pingfm.org pgp key at: x-hkp://wwwkeys.de.pgp.net ----- End forwarded message ----- -- regards ____- joy ________/\---------%%%___________----------- webcast every sunday 2000 cest at pingfm.org pgp key at: x-hkp://wwwkeys.de.pgp.net ------------------------------------------------------- This sf.net email is sponsored by: Dice - The leading online job board for high-tech professionals.
