Alsa has natively supported both the front and rear channels for a number of months now, iirc. > % aplay -Dhw:0,2 foo.wav Yep. That works fine. One of the first things I'm noticing now, however, is that the only Alsa application that seems to use the rear speakers is aplay, and only when specified. For example, alsaplayer will still only use the front speakers. Now, is this something that needs to be set up in the .asoundrc file? Is this documented somewhere? > if it's ok, please try to add the following option to snd-pcm-oss: > > options snd-pcm-oss snd_adsp_map=2 > > so that hw:0,2 is mapped to /dev/adsp. Done. But what exactly does this give me :-) I hate to seem like an idiot, but my only other experience with the alsa drivers is with a SB Live! With the SB Live!, you don't need to take any extra steps to get both the front and rear channels working. I certainly don't remember having to setup anything for /dev/adsp :-) I see a couple references to adsp in the alsa-howto, but nothing that really explains how to set it up and use it :-) > The another possibility is to use ALSA OSS wrapper library. > You can define like this in your ~/.asoundrc > > pcm.adsp0 pcm.rear > > then run program via aoss wrapper. Is this documented somewhere, too? Searching for "aoss wrapper" in google doesn't turn up anything, and the search mechanism on the Alsa homepage seems to be broken (someone might want to remove it till it gets fixed) :-) Sorry if I'm coming off as ignorant, but this is the one area where the OSS ymf drivers are superiour to the Alsa drivers, and I'd love to be able to get it working so I can stop having to switch back and forth between the two :-) Adam _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
