The plugin just create a process chain which copies PCM audio samples from Alsa to the player - it does not manipulate the audio in any way. If the audio is distorted then it is probably distorted from the Alsa subsystem. Alsa will do resampling/conversion if necessary (e.g. usb audio is 96Khz/24 but default waveinput is set up for CD quality 44.1Khz/16bit) if you are using Alsa emulation under Pulse - then IIRC there are a whole lot of other issues that might be affecting audio.
You do not need LMS to test - run the command line that Wavinput generates separately and test with that. ------------------------------------------------------------------------ bpa's Profile: http://forums.slimdevices.com/member.php?userid=1806 View this thread: http://forums.slimdevices.com/showthread.php?t=49584 _______________________________________________ plugins mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/plugins
