Hi Silvertones
The only 2 mixer inputs that are muted are the WavOut S/PDIF an H/W In S/PDIF (which I am not using S/PDIF) and the others including Master Volume are all set to Stereo Link and Solo with gains all the way up. Audio drivers are set to Audio Input--M-Audio Delta AP 1/2....Audio Output--M-Audio Delta AP 1/2. Also using MME at this time in PTPA.
