The output from snd_pcm_status_dump () is as below:
Playback Buffer number:2

I am able to jump but snd_pcm_forward() returns 0. Any sample showing the usage will really help.
Thanks and Regards,

Please find the output from snd_pcm_dump() attached.
Ok, replace snd_pcm_dump() with snd_pcm_status_dump() and send output
again, please. Also, if you can send me (privately) your test code, I'll
try to check it and reproduce the problem.
