Hello:
When using 'mixer_type="software"' in my mpd.conf file, volume can not
be controlled during DSF and SACD ISO playback (ISO support is via
Maxim Anisiutkin's experimental plugin). However, FLAC and MP3 files
work just fine in using the software option for my mixer setting.
Running Linux Mint 17, 3.13.0.-37-generic x86_64. I am using
mpd-0.18.7-1 as well as Maxim's fork (git pull as of 2/14/15). My
client is ncmpcpp-0.5.10-1.1.
Hardware based volume control works fine though with all file formats,
only software based fails with SACD based files. Given that the SACD
files should be converted to 24-bit/385.2k PCM during playback,
shouldn't software mixer based volume control still work?

Is this a real issue or is this pilot error on my part?

PS ffmpeg support also had an issue during the build. The
HAVE_AV_FAST_MALLOC define is a bit wonky. I had to explicitly include
libavcode/avcodec.h to get it to compile. Here is my libavcodec-dev

$ sudo dpkg -s libavcodec-dev

Description: Development files for libavcodec
FFmpeg is a complete, cross-platform solution to decode, encode, record,
convert and stream audio and video.
This maybe another bug in autoconf/m4 macro land.
