But that's not the situation. Qt 5.4 AFAIK fixes the configuration defect that disables ALSA support if Pulse Audio is around but it is down to the packagers for the distribution how they choose to configure ad build Qt5, they have always been able to package a Qt5 that supports ALSA just not one that supports both ALSA and Pulse Audio until 5.4.
Anyway, this is not a matter for WSJT-X, we just use Qt5 and it uses Qt for audio input and output. This should be moot for users that use pre-packaged distributions of Linux since the desktop builds that use Pulse Audio should be ALSA compatible as Pulse Audio provides an ALSA emulation layer via a plugin. If latency is an issue that may be a problem but with WSJT-X latency in the sub-millisecond region is not required. > > 73 > > Nick G3VNC 73 Bill G4WJS. ------------------------------------------------------------------------------ Dive into the World of Parallel Programming The Go Parallel Website, sponsored by Intel and developed in partnership with Slashdot Media, is your hub for all things parallel software development, from weekly thought leadership blogs to news, videos, case studies, tutorials and more.
