That would work in the "default" alsa configuration. It does not work in the generic case as the hw and plughw default devices might be pointing to completely different hardware (for example "hw" might be pointing to the second card in a system, a 24 channel Hammerfall, and "plughw" might point to the first card, a stereo Ensoniq 64 :-) At this point there is no generic solution to finding out the underlying hardware capabilities of a plug pcm, to be able to autoconfigure software. As Paul suggests, search the archives for the long thread on this last fall... -- Fernando _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
