New Forum and new version 4.1. Oh happy day! Thanks Tim.

Suggest everyone stop this DIY, ok while it lasted (1486 posts). Time to migrate.

Hi, NuGuy Audio

Sadly, my Samsung Galaxy S5 has gone missing (that's a whole 'nuther story) so I've been unable to test against Samsung's version of Android. Bluetooth pairing has worked for me with my Nexus 6P phone, Nexus 7 and 9 tablets, and also with various BT speakers. Only my Amazon Echo continues to defy my attempts to pair.

Regards,
Kent

As jonners says, the answer is [n], as I realised after the post

It's just a simple case of not thinking properly and not seeing properly either with all the egg on my face

Long sigh

P.S. I was all the time worried about my bad English when writing then these words.
Your English is very good, don't worry!

So, now i did some more tests and i am trying to put all information about sound quality tweaking in one place.

1. This is a must - wifi off, bt off, hdmi off, volume control off, eq off, resampling off.

2. added in /boot/config.txt :

force_turbo=1
avoid_pwm_pll=1
arm_freq=333
over_voltage=-7
core_freq=166
h264_freq=166
isp_freq=166
v3d_freq=166
gpu_freq=166
sdram_freq=166
sdram_schmoo=0x021e882c
over_voltage_sdram_p=5
over_voltage_sdram_i=3
over_voltage_sdram_c=-13
gpu_mem=16


3. added in /boot/cmdline.txt:

dwc_otg.microframe_schedule=0 dle=0 dwc_otg.nak_holdoff_enable=1 dwc_otg.fiq_fix_enable=0 dwc_otg.lpm_enable=0 smsc95xx.turbo_mode=N isolcpus=2,3

isolcpus is isolating two cpus only for mpd and works only on quadcore pi's

4. changed options in /lib/systemd/system/mpd.service, original value is uncommented:

#CPUSchedulingPolicy=other
CPUSchedulingPolicy=fifo

tried different, for me fifo sounds best.

#CPUSchedulingPriority=43
CPUSchedulingPriority=70

tried higher settings, but 70 is a good compromise

#Nice=-10
Nice=-15

also tried higher values, but -15 is a good compromise

#ExecStart=/usr/local/bin/mpd --no-daemon $MPDCONF
ExecStart=/usr/bin/taskset -c 2,3 /usr/local/bin/mpd --no-daemon $MPDCONF

this one is starting mpd using isolated cpus and no other processes are using those cpus.

My streaming is sounding as good, as never before and now it is clear for me, that underclocking cpus and ram is really great.

Thanks to anybody, who found out, how to "audiophilise" and "de-digitituslise" moOde

Maybe some of those tweaks (which are not making system unstable) can be implemented in moOde?

Suggest you register in the new forum (Forum) if you haven't already done so and post these tweaks there.
