http://bugs.winehq.org/show_bug.cgi?id=29585 --- Comment #8 from Andrew Eikum <aeikum(a)codeweavers.com> 2012-01-24 10:47:36 CST --- Created attachment 38531 --> http://bugs.winehq.org/attachment.cgi?id=38531 OSS playground (C source) Here's a simple test program I put together to test how OSS behaves. I found the following: 1 kHz -> SKIP -> 200 Hz The rest of the 1 kHz buffer plays out, then the 200 Hz tone starts. No silence at all. This seems no different if the SKIP is omitted. 1 kHz -> HALT -> 200 Hz The 1 kHz tone stops immediately, then the 200 Hz tone starts. No silence at all. 1 kHz -> SILENCE -> 200 Hz The 1 kHz tone stops immediately, then silence for the length of the buffer, then the 200 Hz tone starts. 1 kHz -> sleep(2) -> 200 Hz The 1kHz tone stops during the sleep, then some silence, then the 200 Hz tone plays with no delay. At no point did I observe the buffer to "wrap" and re-play old frames. As the last test above shows, OSS4 handles underrun in the same was as MMDevAPI; it just stops the device and restarts it immediately when data is written. No recovery is required. So I believe HALT is the only interesting command (SKIP appears to do nothing at all, and we probably have no interest in inserting a buffer's length of SILENCE). -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.
