[QUOTE="CyberSimian, post: 1288125, member: 141969"] I have done some more investigating of the unintended scheduling problem (but no solution yet). Some points: (1) Initially I thought that this was a problem with the SPDIF digital audio output. But I have now tested HDMI with sound effects enabled on MP 1.29, and HDMI exhibits the same unintended scheduling. :( (2) [USER=128337]@joecrow[/USER] tested his system with the testcase described below, but he did not find a problem. :) :confused: (3) I have MP 1.24 installed on both 32-bit and 64-bit Windows 7 in separate partitions on my HTPC, so I tested those. Both versions of MP 1.24 exhibited the problem. :( (4) I have MP 1.18 installed on 32-bit Windows 7, so I tested that. [b]It did NOT exhibit the problem.[/b] :) (5) I compared the "MediaPortal.xml" files from MP 1.29 and 1.18, but they are too different for the comparison to be useful. However, this did lead me to look at the volume OSD (the setting for "defaultVolumeOSD" differs between the two files). (6) I enabled the MP volume OSD, and noticed a strange effect: (a) On the "Home" panel, using the UP/DOWN buttons: [LIST] [*]Moves the focus immediately. (y) [*]Plays the button sound effect immediately. (y) [*]Displays the volume OSD immediately (the OSD stays on screen for 4 seconds). (y) [/LIST] (b) On the "Upcoming Episodes" panel, using the UP/DOWN buttons: [LIST] [*]Moves the focus immediately. (y) [*]Plays the button sound effect immediately. (y) [*]Displays the volume OSD [b]1.5 seconds after the button press[/b]. (n) :mad: [*]Displays the red dot [b]1.5 seconds after the button press[/b]. (n) :mad: [/LIST] (7) I tried all combinations of enabling and disabling the MP volume OSD and the Windows volume OSD, but all combinations exhibited the problem. (8) I still don't know what is causing this problem, but the fact that the display of the MP volume OSD is synchronised with the unintended scheduling, and [i]not[/i] synchronised with the playing of the button sound effect, suggests that the problem is related in some way to the processing of the volume OSD (well, maybe). If one of the developers wants to investigate this, I will produce a log file, but I think that extra debug logging will be required, as the current debug log does not provide much of a clue (see the log file attached earlier). It seems that this problem is dependent on MP settings, or Windows settings, or the HTPC hardware, so it may not be reproducible on other systems (it may be that I have a particular combination of hardware that causes this problem to occur). Does MP have a sound expert? [USER=50482]@azzuro[/USER] ? -- from CyberSimian in the UK [b]Testcase:[/b] Note: it does not matter if your system suffers from the "silent stream" bug. [LIST] [*]Start "MP Config" and enable skin sound effects and the MP volume OSD. [*]Start MP and display the EPG. [*]Select a programme that is in the future and which has several occurrences in the EPG, and press the OK button. The "Upcoming Episodes" panel is displayed. [*]Wait for 10 seconds to see if a red dot appears adjacent to the episode that has the focus. [*]Press the DOWN button and again wait for 10 seconds. If you suffer from this problem, a red dot will appear on the item that has the focus. [*]Press DOWN again and wait 10 seconds. Another red dot appears. And so on. [*]If you now press UP, the red dot is removed. [*]At the end of testing, remember to disable skin sound effects, and cancel any of the unintended recordings that are still scheduled.
