Hmm, it should work. Please check the botic configuration values:
grep . /sys/module/snd_soc_botic/parameters/*
and also the "aplay -l" output.
If there is no Botic sound card, then the dtb= selection in the uEnv.txt does not work as intended. A workaround could be to replace am335x-boneblack.dtb by am335x-boneblack-botic.dtb file.
cp /boot/dtbs/4.5.0-botic7-rc1/am335x-boneblack-botic.dtb /boot/dtbs/4.5.0-botic7-rc1/am335x-boneblack.dtb
grep . /sys/module/snd_soc_botic/parameters/*
and also the "aplay -l" output.

Hmm. I've tested the record only with internal BBB clock. There might be an issue.
Does the playback work for you? It should be clocked from the same clock.
Please retry with the concurrent playback of the same sampling rate.
I have it sorted and it was very simple!
I already have Squeezelite installed on top of my Botic driver. Seems it was as simple as enabling Squeezebox support within Roon and including the IP of the roon server in the squeezelite startup command using the '-s' argument to define a specific server.
So my squeezelite startup string now looks like:
squeezelite -o hw:CARD=Botic -n JRdddac -a 16384:1024:: -s 192.168.1.27
And my Roon now looks like
An externally hosted image should be here but it was not working when we last tested it.
And beautiful music is filling my room from my BBB Botic > Hermes > Cronus > DDDAC player. Happy days!

Any comments please regarding the sound quality of Roon (500$ ??) compared to the MPD (0$ ;-) ? Is Roon worth its price?

If you want to control your BBB via oldschool infrared TV remote, you can try it with this LIRC driver:
https://github.com/miero/lirc-bbb
For compilation of the kernel driver for botic7-rc1, you will need to install also a DEB with headers:
http://repo.ieero.com/botic/pool/ma...ers-4.5.0-botic7-rc1_4.5-botic7-rc1_armhf.deb
Enjoy!

There is no sound quality difference. Roon doesn't replace mpd, nor is it just a remote control tool. I already have remote control and Spotify /Tidal integration via Squeezelite and LMS server. I paid the $119 annual cost for Roon because of the experience of exploring, finding new music and even old music I have forgotten. I enjoy reading the biography of the artists and albums, making connections and learning. I also love the radio functionality where it will continue playing similar tunes when a playlist has ended. This week i have enjoyed my existing collection and heard new things I would not have done otherwise via Tidal and I have expanded my musical education, and for me that is well worth the cost of 1 cd per month
Anyway, this has been discussed at length many other places so I won't take this thread off track, just to say I am very pleased that Roon>Squeezelite >botic>hermes >cronus play together so nicely

Hi, thanks for making this!
I have installed headers, but when I try "make prepare" I get this:

make -C /lib/modules/`uname -r`/build scripts
make[1]: Entering directory `/usr/src/linux-headers-4.5.0-botic7-rc1'

Any idea what I'm doing wrong?

I tried using 'root@beaglebone:/# dpkg -i linux-image-4.5.0-botic7-rc1_4.5-botic7-rc1_armhf.deb'
It ran. There were three errors reported and I am investigating them now. I imagine (hope!) they are inconsequential.
a) temperature-mod
b) debugss-mod
c) cmem-mod

Hmm, that I see. You need at lest gcc version 4.9, but that one is not available for Debian Wheezy.
So, I've prepared compiled version for you. You can install it on the BBB:
After the reboot, the /dev/lirc0 should be available (if it is added in the /etc/modules).
Hi guys,
How do I get the botic build to have a different default sound output device?
I am trying to set botic to give 2 split channels (left and right) of right justified data output and I think I have the necessary work done, but I don't know how to set this new botic-split device as default output.
I have edited the /boot/uboot/uEnv.txt so the last line looks like this:
I have created an alsa output device which splits left and right by creating a /etc/asound.conf file with this in
and aplay -L lists 'botic-split' as an output
I have edited /etc/mpd.conf to have a new audio output option.
But I'm stuck on the final hurdle, because I can't work out where the default output is set or how to change it.
Any pointers gratefully received
James

Greetings James,
This is probably going to seem like a sketchy reply - sorry - but in practice ALSA can be fairly sketchy. Clearing things up could take us far away from Botic per se. So, depending on the following, I may suggest that we move to a thread in which ALSA is the topic.
ALSA can do that, no problem. If you want to proceed, let me know and we'll pick up the ALSA discussion here: http://www.diyaudio.com/forums/twisted-pear/277564-ladspa-filters-digital-crossovers-bbb.html
Looking at and copying working ALSA syntax is one of the most effective ways to get things functioning.

Botic doesn't specify the output device. The applications that run under Botic typically do so. Some applications will not accept ALSA plugins as output devices, but can accept 'hardware' output addresses (the correct term escapes me at present) like 'hw:0,0'. Unfortunately, I have never gotten MPD (nor Ecasound) to accept anything other than such addresses that bypass ALSA's programming space. That is why in my own system I am using squeezelite, because it does permit output to ALSA plugs. If this limitation of MPD is a deal breaker, then I can't help. You mentioned configuring squeezelite for Roon. If squeezelite is part of the system about which you inquire, then chances for success are good.

Try it again without gpio_in_pin parameter and check the kernel log:
If it does not work, please post here the dmesg output with the parameter.
I'm having same problems as Bern.
Lirc0 is only showing in /dev when I only add "lirc_bbb" in /etc/modules:
Tried to run dmesg | grep lirc:
It says that reciever is connected on GPIO pin 60? That is on the P9 header.
I have connected my IR-reciever on GPIO pin 66.
Does this have anything to do with line 81 in lirc_bbb.c?:
