This I wrote at the bottom of page 284: it explains why I do not understand where to edit these settings now.

From the old Botic I had to mount "/boot/uboot" and edit uEnv.txt" to be able to set the correct optargs parameters.
Is this still neccesary ? ... when I do so the uEnv.txt file is empty but when I do not mount it and edit /boot/uEnv.txt there is a lot in there but no "optargs" line

What are the correct steps to set these parameter ?

In /boot/uEnv.txt I see:
cmdline=coherent_pool=1M net.ifnames=0 quiet
#cmdline=coherent_pool=1M quiet snd_soc_botic.clk_44k1=45158400 snd_soc_botic.clk_48k=49152000
#cmdline=coherent_pool=1M quiet snd_soc_botic.clk_44k1=90316800 snd_soc_botic.clk_48k=98304000

Is this related ??

If your DAC has no onboard clock, the clock on BBB, which is 48K only, becomes MCLK (i.e., 44.1K clock is not supported). Modify the kernel option in uEnv/txt by adding "snd_soc_botic.ext_masterclk=2" just after "cmdline=coherent_pool=1M quiet" and there will be no need to add "snd_soc_botic.clk_blah_blah".

This means 44.1K sources will be played with different rate. The details are well described in the section of "Clocks configuration".

Rgds,

I have 2 Beaglebones for testing.
One with external clock for 44.1 and onboard for 48k which I used so far (Botic 4)
The other has a hacked XMOS USB receiver board from which I re-used the dual clock section which I want to use now

I know what values I have to set for snd_soc_botic options from the Miero page.

I was used to see optargs= ... blabla
Apparently now it is similar options but now I put the options after cmdline=

My earlier question about the socket error I was experiencing at "systemctl status mpd.service" :

Aug 09 10:15:12 arm mpd[1910]: Aug 09 10:15 : exception: bind to '0.0.0.0:6600' failed (continuing anyway, because binding to '[::]:6600' succeeded): Failed to bind socket: Address already in use
root@arm:/home/debian#

From /etc/mpd.conf:
# For network
bind_to_address "any"
#

Rgds,

If I change "any" to "0.0.0.0" (like was mentioned in the first BeagleBone topic at ComputerAudiophile.com - I guess that was in 2013) the error is not shown

Ignore my latest reply above ... It does not give conclusive results so I am not sure what causes the random problems ... need to investigate further

If you are still persistent with this issue, then try this one: systemctl disable mpd.socket. Enabling this socket is the culprit, though I don't care.

I am already past this “error” but still have some other issues but stopped for now.

I was probably naive thinking I solved the “bind-to-address” warning message as I really have limited linux knowledge and mainly do trial-by-error if it gets over my head.

I will try to pinpoint my other issues and report back later.

As the original issue was mpad no longer working, why not use soundirok instead. I needed to do the same change and like soundirok much better. No need to change anything on MPD.
