Hi All,
I have download and compile latency.c application from http://www.alsa-project.org/alsa-doc/alsa-lib/_2test_2latency_8c-example.htm.... This application is working fine on Linux PC. But when I am using this application on my omap4 board(using ubuntu10.10) is not working.
I am getting"Streams link error: Function not implemented" error. I debug the application and found this error coming from the *snd_pcm_link* function. I am using ALSA Driver Version 1.0.23.
please find pointers.
Thanks in Advance Ashwani
Hi, Bringing to Top ,anyone faced similar problem of "snd_pcm_link" returning error val=-38 and prints "Streams link error: Function not implemented".
I don't know of such a problem. Better to check what went wrong via strace or such.

when i am executing this apps getting "underrun occurred" error CPU consumption very high 22 - 27%.

Thanks in advance Ashwani
