Hi!
Has at least somebody a hint for us, where we can find a solution for our problem? We searched already in mailing list and internet but could not found something fitting. And the list of release changes is very long and descriptions are not always very clear.
Kind regards

Hi!
We had to write a driver for audio playing and recording on Linux thin clients. We are using ALSA driver + libs for it, but we are depending on the versions which are installed on them.
We have a certain buffer size for this and set the corresponding hardware and software parameters and call for capture snd_pcm_readi(). The function returns the read buffer frames. In most versions this is equal to the number of wanted passed frames, but not in all. We have ALSA driver version 1.0.15 and 1.0.22.1 where the returned number is the same. But we have also version 1.0.21 where the returned number is the period size or a multiple of it.
So conclusion is, that something was changed between 1.0.15 and 1.0.21 and changed back till 1.0.22.1. As we are dependent on the behaviour of the former and newer version, my question is, if there is a possibility to get the same behaviour in version 1.0.21?
Thank you for your answer in advance!
