So it is on ALSA, too. Theoretically more could be, but it seems that the (only one) DSP code provided from ESS has a bug. > So, is this the default behavior?

Unfortunately ESS is famous to provide the only minimum information, so far. I hope this will change in future.. ciao, Takashi _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
