commit 322c7150b25ebd2c4c2bd4e3abbe0978f66f3737 Author: Takashi Yano <[email protected]> Date: Sun Sep 17 08:49:34 2023 +0900 Cygwin: dsp: Avoid setting buffer that is too small. The buffer size that is too small causes choppy sound. That is not practical at all. With this patch, the minimum value of the buffer size (i.e. fragstotal * fragsize) is restricted to 16384 bytes.
