Important notice for all who wants to use Right-Justified data format.

It does not work with the current driver. I'm going to try fix this in the next few days.

For Buffalo 3 users:

To play at max. volume with non-jumpered input channels on B3 it should be enough to set following:
- snd_soc_botic.serconfig="M-M-"
- enable channel remapping feature on the B3
- convert 2 channel data into to 4 channel audio

(verified with PCM only so far)

I expect "MDMD" value will be needed for PCM+DSD support.

The work you are sharing and the support you are offering are very generous. I suggest two small additions to the Botic home page:

1) A paypal 'donate' button! ...if only to help a little with your equipment and other costs... When I get set up I will use it! ...and I am sure that other users appreciate your work as much as me.

2) A statement on what you would like to provide as Botic support - the questions are only going to come more frequently and be more diverse!

I am curious about your vision for the future - What features would you like to add? This might help focus contributions from others toward the community of knowledge and open source code. [From the obvious to the sublime? ...perhaps I2C reports of player status, or IR sensor integration...] What will the 'finished' product be like in your own system?

Cheers ,

The 'donate' button is not planned. But I'd be glad if you could help with your donation to some local charity or voluntary association :-)

OK, I'll add something on the page. Thanks.

Hi Miero,

I second the proposal of Frank. I guess a lot of people will be glad to support you for the time you put in this project, including me.

I have noticed that quite an amount of my music files on my NAS is not indexed in the library. Even after repeatedly updating.

I have all my albums stored in separate folders and subfolders, mostly Flac files and some wav and mp3.
I can't figure out why some albums will not be indexed. These will index fine on my other streamers: Runeaudio, Volumio, LMS, MPDpup.

I have also noted that the albums (album artist names) are indexed differently from my other streamers, messing up the order in album list.

Is this a known bug? Do you have any advice on how to solve this?

Kind regards,

Default botic v5 update

Something like updated Botic driver is ready for testing...

- fixed Right-Justified output mode (use snd_soc_botic.dai_format=16386)
- (EXPERIMENTAL and ugly) support for ALSA mixer controlled by /sbin/botic_helper
- should support USB memory sticks now
- probably fixes broken networking at boot
- new kernel 4.0, thus new features and new bugs

(for botic v4 or boticized volumio users only)
apt-get update
apt-get install linux-image-4.0.0-botic5

after reboot kernel version should be...
root@botic:~# uname -a
Linux botic 4.0.0-botic5 #1 PREEMPT Tue Apr 28 23:42:17 CEST 2015 armv7l GNU/Linux

(optional installation of I2C volume helper for ES9018)
# verify that ES9018 is readable
i2cdump -r 0-31 -y 1 0x48 b
# install helper
cd /sbin
chmod +x botic_helper

(now try the volume mixer)
# enable helper (you can add this to /etc/rc.local)
echo "/sbin/botic_helper" > /sys/module/snd_soc_botic/parameters/helper_cmd
# try to adjust volumes

Botic v5 sources:

Enjoy and report if it does not work. Thanks.
