Cross" To: multimedia@freebsd.org Subject: Stuttering in Mpeg3 playback Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-multimedia@freebsd.org X-Loop: FreeBSD.org Precedence: bulk I have noticed a distinct 'stutter' in soundplayback on mpg123 using OSS/FreeBSD 3.8h with an Ensonq Soundscape Elite. The problem is that if the machine is running even with a moderate load the sound playback suffers small skips (even if the processor still has as much as 25% idle time). The problem is also noticible in X if I just switch focus by moving the mouse. (moving the mouse without changing focus does not cause the skip). It seems like the card is not being saturated with data. This is odd, because with a 64K DMA buffer (I believe the default with OSS), it should be a full 1/3 second of buffered data. Has anyone else experienced this. Is it a problem with my soundcard, the kernel, or OSS? -- David Cross
