I have a pair of modified Parrott Zik3 headphones, adapted for those with hearing problems (mainly giving separate equalization for each ear matching an audiogram) called PYOUR. Having used them for a while with my laptop (and squeezelite) I thought it would be useful to try them with the Touch and EDO and a USB connection to the headphones. This is specified for the headphones as being 24/48000 on USB.
As is so often the way for me, I didn't start with quite standard settings (I had C-3PO using pcm/wav on the Touch from past uses), and so went round almost all the options, always getting either noise (with pcm/wav) or crackly sound (with flac). I tried all 3 available non-standard kernel options, the USB 1 hub workaround, a USB hub (no workaround), different buffer sizes, and so on. On the point of giving up I went back to basics (but still with C-3PO). With no hub, no workaround, standard EDO kernel, standard buffers, flacs supplied at 48000, it all works fine! If you wonder why I'm using C-3PO for this, one reason is that my limited hearing means I have to constrain the dynamic range a bit for my type of music. Classical stuff tends to have very quiet bits and very loud bits in one piece. To be able to hear the very quiet parts I need the volume to be increased, which causes the loud parts to damage my hearing even further. The sox compand options allows me to compress the volume just a little, and enough to be sensible so that I'm not adjusting the volume all the time. The headphones are a great boon for me, allowing me to hear things I can't normally hear without hearing aids, and with much better quality than the tiny speakers inside such aids. Not using my laptop means I spend less time distracting myself tapping on the keyboard looking at forums, news and such! So I must now shut the laptop down and get back to the Touch.
