Hi,
I am using the pcmhandle provided by ALSA as one of my sound output devices.
I've encountered with weird situation where I am trying to play a steady sin wave, the device plays a wrong output it almost sounds like some buffer was became 0.
In this situation I tried use the speaker-test binary to see if my own buffer was corrupted, but still sounded the same.
Unless I close the handle that I've bee using for last 4days, I couldn't recover. I tried to use the snd_prepare to see if it can comeback, I looked for underuns and overuns but they never happened.
I honestly am clueless on what to do, pease share your insight for me. thanks
