Hi,
I am using Intel8x0 driver for my sound card. During data transfer from user to driver, I am trying to collect the buffer. I have implemented .copy function and also disabled the mmap.
If I disable the mmap in .info structure, i get an error that the device is in use. If i try getting the debug messages; It fails in snd_pcm_common_ioctl1 for SNDRV_PCM_IOCTL_HW_REFINE.
Can anyone please guide me on to the right path of implementing what I want to do.
Does the error occur even if you access via "hw:0", such as, % aplay -Dhw:0 foo.wav
?? If yes, there is some incosistency between the hardware configuration and the implementation...
