This fixes use of multiple MIDI outputs while keeping the flexibility of proper ALSA sequencer port subscriptions.
Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=52220 Signed-off-by: Jacek Konieczny jajcus@jajcus.net --- v2: do not fail on port connection errors. Fixes failures to open a device when the port is already connected to the target, either by wine or some external application --- dlls/winealsa.drv/midi.c | 55 +++++++++++++++++++++++++++------------- 1 file changed, 38 insertions(+), 17 deletions(-)
