Hi,
I am working on Davinci6446 OSS sound driver. This sound driver doesn't
support full duplex mode.
To do audio loop back, I have created two threads - Read_Thread
and Write_Thread.
static void *Read_Thread(void *parm)
{
here I have open the device "/dev/dsp" in O_RDONLY
open( "/dev/dsp", O_RDONLY );
set the configuration for driver
}
static void *Write_Thread(void *parm)
{
here I have open the device "/dev/dsp" in O_WRONLY
open( "/dev/dsp", O_WRONLY );
set the configuration for driver
}
I have some question regarding this :
1. Does I need to configure the device in read as well as in write mode?
2. If yes, then can I configure the device as MONO in read mode
(Read_Thread) and STEREO in write mode (Write_Thread).
can I configure device to use block size = 256 in read mode (Read_Thread)
and block size = 1024 in write mode (Write_Thread).
Regards,
Prashant Muley.
