I have also attached the snippet of output of dmesg command. Our application requires to make use of ESS Solo-1 audio card in Audio-2 Native mode with auto initialize DMA. Also our application just need to implement playback function. In the case of double buffering, The DMA count we get at the first is half of the total Buffer size ( In our case its 64K), But we have observed that the DMA address and DMA count changes everytime we install the module in the kernel. Also we are not able to figure out what should be the value of Audio-2 Transfer Count Reload registers? When the module is installed several times, we observed that the DMA address and DMA count changes everytime we install the module. However it seems that interrupts are getting generated properly, but DMA address does not change. as far as I understand interrupt should be generated for the transition between the buffer halves. Waiting for the good news, :) -Vikram Quoting Jaroslav Kysela <[EMAIL PROTECTED]>: > On Mon, 12 Aug 2002, [EMAIL PROTECTED] wrote: > > > Hello ALSA Maling List, > > > > We are developing the custom application which uses ALSA for > the > > application user-space.
