Yes, you're right. libFlac doesn't have any special configure options. But what is the difference between your and alahn's version of libFlac?
You can replace libFlac.so with specified above and you'll see significant fall of CPU load.

For comparison, I compiled libflac from the stock flac-1.2.1 source distribution using:

./configure CPPFLAGS="-Wall -O2 -march=mips32r2 -Wa,-32 -Wa,-march=mips32r2 -Wa,-mips32r2" --prefix=/usr --host=mipsel-linux --target=mipsel-linux --disable-3dnow --disable-altivec --disable-asm-optimizations --disable-rpath --with-gnu-ld

Nothing special there.

Also as far as the plugin, the previously released/recompiled one is still fully compatible with the official 0.15.9 mpd release. I've made the necessary changes for the current 0.16 development git pull current as of Apr 4 which adds experimental 24-bit packed sample support. Plugin for 0.16 git pull on Apr 4.

I'm still trying to squeek out some time to get back to the recompile for SDK 3.7/3.8 for the 200 series, but something always keeps coming up on the weekends.

That is great, Alan. I will be sure to try it out once the development 0.16 mpd is packaged. Thanks very much for taking the time to do this, it is much appreciated.

And thanks to Shadowcode too for the effort in getting the release nicely packaged up.

Hi all.

Is it possible to configure mpd or audio output plugin in such a way that the optical output is always 16/44.1, regardless of the format of the file being played?

[alanh]

It's possible but the S/P-DIF output operating in PCM mode picks it's data up from the I2S outputs, so the DACs and HDMI will have the same parameters fixed. And the Sigma audio DSPs on the 863x are -->horrible<-- at re-sampling. They use a single tap so they do very little if any anti-aliasing. You really wouldn't like the results.

[glorifyday]

That's a bad news for me :-(.
I thought of using Theta Generation Va DAC and it accepts only 16/44.1.

Maybe a software solution is possible?

Why then don't you just convert your music to 44.1/16? dBPoweramp or r8brain.

I would not like to keep two versions of each file that is not 16/44.1...
Anyway, this is some option.

Then go for a DAC that plays true High Res.

I can give positive advice on the Naim DAC .

[glorifyday]

The newest one?

Well... I did compared a used Theta with many new and old DACs available at the same budget. None of them gave me this "something".
Anyway, I will still try some other hi-res DACs, maybe I will find some alternative...

Sorry for the off-topic.

Is there a Linux client which is able to show the currently played song information from last.fm? I tried gmpc on my Ubuntu box and this client also does not show any further information.

Actually, it's PHP client that can decode META data from radio streams. As for clients on PC.. I use QMPDclient which shows NOW-PLAYING from radio streams.

Hi again.

I found out that the latest mpd is compiled with libsamplerate support.
Then, what will happen if I write in the config file:

Code:

audio_output_format "44100:16:2"
samplerate_converter "Best Sinc Interpolator"

Hi Geerten,
I tried my USB conection to my Havana DAC but it wouldn't play although the optical output works fine. Did you do something to get the USB to work? USB would be my preference.

Best,
Ed

My mpc-client reports a 0.15.0 version for the mpd-server.

Is this a mistake in the version number used in compiling the 0.15.9 or has the wrong version been taken from the git.

Minion shows 15.0 for mine as well. Is this correct? Looking at the Community Installer it only lists 15.9.

Thanks,

-Downloaded the package mpd-nmt-20090222.zip. (This is the version currently in CSI.)
-Copied the subdirectory "modules" from that package under /share/Apps/mpd
-Pasted config for OSS-output into /share/Apps/mpd/etc/mpd.conf (from the mpd.conf in that package)
-Pasted lines to load OSS modules into /share/Apps/mpd/daemon.sh (from the daemon.sh in that package)
-Restarted mpd

If the USB-output is the only one you need, and you don't care too much about having the latest mpd, you could also just install that CSI package.

GMPC from the the PC also reports 0.15.0

[shadowcode]

I think it's either a bug in MPD or MPC;

Code:

root@mediatank mpd# LD_LIBRARY_PATH=lib bin/mpc version
mpd version: 0.15.0
root@mediatank mpd# LD_LIBRARY_PATH=lib bin/mpd -V
mpd (MPD: Music Player Daemon) 0.15.9

MPD itself reports 0.15.9, so I'm pretty sure that's the correct version.
