Support for Botic Linux driver

Duffy Moon:

what about this one?

speaker-test -Dhw:0,0 -c 2

I get:
Code:
speaker-test 1.0.27.2

Playback device is hw:0,0
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 128 to 32768
Period size range from 8 to 2048
Using max buffer size 32768
Periods = 4
was set period_size = 2048
was set buffer_size = 32768
 0 - Front Left
 1 - Front Right
Time per period = 5.296016
 0 - Front Left
 1 - Front Right

and it continues. The DACs lock but I hear nothing from the headphones (which I checked in case there was a fault).

Oddly, I'm now seeing:

Code:
ERROR: Failed to open audio output

What about botic driver configuration?

Are there default parameters, or did you have something non-standard? E.g. what is printed by these commands?


aplay -l

cat /sys/module/snd_soc_botic/parameters/serconfig

Code:
root@botic:~# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Botic [Botic], device 0: external dac-hifi-0 []
  Subdevices: 0/1
  Subdevice #0: subdevice #0

Code:
root@botic:~# cat /sys/module/snd_soc_botic/parameters/serconfig
MMMM
 
Regards, Duffy. I am not an expert but I am learning slowly by trial and error.

Show us the result of 'ps -A'

This is every process your software is running. If I try to run speaker-test while squeezelite is also running, I get 'device or resource busy'. ...though MPD is usually not a problem when it runs unneeded. ...still, perhaps there will be a clue, like a duplication, etc.
