| sound.cpp: Fix missed samples due to state save (#9917) (#9918) * sound.cpp: Fix missed samples due to state save (#9917) The PR address #9917. A save state may occur between time slices. Sound devices through sound.cpp are updated during a timer call every 20ms. When the state is saved, these devices are not updated to the current machine time. Consequently after a state load the devices have have a "time lag" since in postload buffer end time is forced to machine time. This change will save the last buffer end time so that all outstanding samples are processed. This is a core change. I tested it on some drivers. This needs a very thorough review and I post the PR primarily to document a possible solution. * sound.cpp: use "stream.sound_stream" as module name for save_item * sound.cpp: use presave handler to store end_time() |
