I was fooling around with my PS3 music settings the other day, and realized the output freq. was set to 48 KHz. This isn't really ideal for playing music CDs, correct? I went ahead and switched it to the 44.1/88.2/176.4 setting. My receiver will handle 44.1 fine, so I'm in good shape. I'm wondering about the bitmapping setting though. Does this only matter if the PS3 is upsampling? For example, a CD is 44.1, the PS3 is outputting 44.1 and no upsampling is occurring, right? So should I just leave bitmapping off, or is it actually doing something even when output is 44.1?
