I am running Squeezelite 1.6.5 on a Raspberry Pi model A+ with the latest firmware and Raspbian with audio out through the headphone jack.
Controlling the volume solely through LMS, the volume is quite low with significant hiss up to about 75% volume. Beyond that point the audio mostly overpowers the hiss, but on pausing playback the hiss is still quite noticeable. Playing the same mp3 through other software locally on the pi, for example omxplayer, results in much better sound at all levels than via squeezelite. Even at low levels (controlled by +/- key bindings during omxplayer playback) it sounds pretty good. Not perfect, but about 10 times better than through Squeezelite. I've tried playing with alsamixer and .asoundrc files. Alsamixer seems to have zero impact on squeezelite. What can I do to bring Squeezelite playback audio quality up to the same level of quality of omxplayer? For this particular project, I prefer to avoid installing a separate DAC. I am going to use a small class D external amplifier and can just jack up LMS to a fixed 100% volume and control it via a pot in my project, but I would like to achieve the same audio quality that the pi has proven itself capable of producing through other software. I've had the same results with Picoreplayer. I prefer Raspbian for the moment due to the wider variety of additional packages available for it, but I could make Picoreplayer or another distribution work if they solve the hiss problem. ------------------------------------------------------------------------ patja's Profile: http://forums.slimdevices.com/member.php?userid=63755 View this thread: http://forums.slimdevices.com/showthread.php?t=97046 _______________________________________________ unix mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/unix
