Hi,
I currently don't have a lot of Rockbox time (exams), but decreasing the
delay when changing volume on the Onda VX747/VX777 has been a much asked
feature (+ I'm personally annoyed by it).
The Ingenic Jz4740 doesn't have hardware volume control in the audio
chip, hence the need for a software-based one. I have currently
implemented this by adding another parameter in the DSP (grep
HAVE_SW_VOLUME_CONTROL apps/dsp.c), but this results in a (pretty long)
delay when changing volume.
AFAICS this can be resolved by decreasing the DSP buffer size, but I'm
guessing that isn't a proper solution. Perhaps this can be solved in an
other way that I missed, any ideas?
Thanks,
Maurus Cuelenaere
