Audio tools for your rescue
It’s quite a necessary to check the output buffer before delivering it to kernel/hardware device. Generally, it’s a good idea to write all the sound buffer into a file before delivering to audio framework (for example ALSA) and copy that file and play it in PC. How can we play a raw data given to ALSA?
There is a really good tool out there in the market called GoldWave. It helps to play raw PCM, ISDN, ASCI data with respective bits and bit order of little and big endian.
