This intrigues me, on my pCP Pi2 with IQAudio DAC and Pi Display the VU meters frequently slam up against the 3+dB. So I dug out my old Denon Audio Technical CD and ripped 2 tracks of 0dB 1001Hz Sine Wave, Left Channel then Right channel. I have attached these as a zip file. Be very careful of them, make sure that the amp is turned down low if you play them. You should be able to accurately measure the output on the VU meters on the Pi Display and maybe there is an ALSA setting that should be made or else the volume on the server settings/player. I have not played the tracks yet, I will later today and will compare the VU screen on a touch and the pCP. +-------------------------------------------------------------------+ |Filename: 19 Denon - 1001hz Sine Wave 0db R.zip | |Download: http://forums.slimdevices.com/attachment.php?attachmentid=19399| +-------------------------------------------------------------------+ A camel is a racehorse designed by a committee. ------------------------------------------------------------------------ Wirrunna's Profile: http://forums.slimdevices.com/member.php?userid=3225 View this thread: http://forums.slimdevices.com/showthread.php?t=97803 _______________________________________________ unix mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/unix
