I've GOT it!!
First off thanks to Klaus (soundcheck), his TT 2.0 mods led me where to
find the files needed to make this work.
Also I'd like to thank Kevin at HRT for the loan of the Streamer II. It
would have been very difficult to do this without it.
Quick summary:
use 50000 for the buffer size, set sample bits to 32 instead of 24 and
set the asound.conf to use HW mode instead of plug mode.
First off this works for the HRT Music Streamer II, and probably for
other async DACs since many of them were reported to have the same
problems the music streamer had.
First the changes to the asound.conf file:
pcm.usbdac {
type hw;
card 1;
}
ctl.usbdac {
type hw;
card 1;
}
pcm.!default usbdac
This is even simpler than it was before, there is no plug layer. Change
the card num to be whatever your DAC is.
Then there are two files to modify:
/usr/share/jive/applets/SqueezeboxFab4/SqueezeboxFab4Meta.lua
and
/etc/squeezeplay/userpath/settings/SqueezeboxFab4.lua
Type:
cd /usr/share/jive/applets/SqueezeboxFab4
vi SqueezeboxFab4Meta.lua
scroll down to the line that starts with:
alsaPlaybackBufferTime
Change the value to 50000. Put the cursor under the left char of the
number, then press the X key until the number is gone. Then type the I
key and type the new number. When done with the new number type the ESC
key.
Scroll down to the alsaSampleSize line. Change the number to 32.
Then find the line with
settings.alsaPlaybackBufferTime
Again set the value to 50000
Now type
:wq
Next edit the other file:
cd /etc/squeezeplay/userpath/settings
vi SqueezeboxFab4.lua
change the alsaPlaybackBufferTime to 50000 and the alsaSampleSize to
32
:wq
reboot
This will restart and hopefully the async DAC will work now.
One interesting thing I found was that after doing this to get rid of
the ticks and pops, soundcheck's TT 2.0 mods make a huge difference
with the Streamer II. Just don't do the buffer change command, or the
USB change, use the above for those.
These mods shouldn't make any difference to an async interface, but it
does, and its not subtle. This one should be obvious to just about
anybody. I don't know how it will affect other async DACs, but I can
say that with the Streamer II it was major.
Have fun!
