Hi there,
I have a Hidizs S9 that I bought ages ago for use with my phone, but I haven't used it much because I've never really managed to get it working right. It has a lot of hiss at low volumes when not using exclusive audio mode apps.
It's a kind of swish noise that fades up as the track starts, and then remains underneath the music. Most noticable in quiet bits.
Yes, this can be solved by using exclusive audio access in something like Hiby Music, UAPP or Fiio Music, but I don't like those apps. I find the user interfaces fiddly and the volume increments can be too coarse when using exclusive USB access. I'd really like to use it with Poweramp. I can already hear people crying "it's the Android audio subsystem doing resampling!". It can't be resampling if it happens even with 48Khz source files, can it? Also the problem doesn't present with other USB dongles, e.g. the Whizzer DA1 is fine using the Android audio subsystem and Poweramp -- completely silent background...
Does anyone know what might be causing that hiss?
Thanks!
