From 8dd2f36f317569665e454268a2677cfba3e848f1 Mon Sep 17 00:00:00 2001 From: Andreas Eversberg Date: Sat, 2 Aug 2008 22:51:52 +0200 Subject: mISDN: Add feature via MISDN_CTRL_FILL_EMPTY to fill fifo if empty This prevents underrun of fifo when filled and in case of an underrun it prevents subsequent underruns due to jitter. Improve dsp, so buffers are kept filled with a certain delay, so moderate jitter will not cause underrun all the time -> the audio quality is highly improved. tones are not interrupted by gaps anymore, except when CPU is stalling or in high load.
