Hi,all: I want to enable dmix for our sound card.Unfortunately for some reason the sound card driver don't support 'mmap' way,it only support 'copy' callback to copy data from upper level to DMA.So ,I think maybe I can modify the alsa-lib dmix source code to let it use 'copy' way to send data to the driver. Is it possible？Could you please give me some ideas? Thanks a lot in advance.
