Failed to open mixer for 'Botic'

This should be just warning. Which player have you used?

With SD image booted on BBB it should work out of the box. You can try either MPD or command line wrappers playdsd64 and playdsd128.

Hello,
I followed your tutorial and tried to play the media which is in the distrib.
It starts to play 4 secs and then stop afterwhile i had a look to the mpd logs where i saw that message.
No error with playdsd64 and playdsd128 but it is stopping after 5-10sec. Do I need to have the DAC plugged in ?

no, you need to provide your file... demo on the disk is just as short ... DSD files are huge! :-)

Ok i was confused by the time displayed by MPD...:)
With mine it seems to work ...
Do I have a picture of your setup with the BBB and the DAC ?

Hi dabrain

I am using 2 TPA OTTO-II to select the required CCHD crystals and to switch between PCM and DSD. The I2S signals are sent to the DAC via a LVDS-HDMI adapter. I have tested the above setup on Buffalo III, Wyred DAC2, DIY TDA1541A and DIY AD1865 with great success.

Hope this helps

Hi,

i read the thread but maybe i did not find it:

is there a way to use this with wireless connection or only for ethernet cable?

thx

drone: I'm connecting to BBB via Ethernet.

The USB WiFi dongle (supported types by native kernel drivers only) should work too, but I'm not sure how it would influence audio performance. When WiFi dongle was close to DAC there was real degradation of sound, so some extension cable have to be used.

Also there was some issues USB wireless keyboard and HDMI at the early stage of development using original beaglebone kernel. But this might be fixed now... or not.

I have very good experiences with an external TP-LINK, for example the TL-MR3020. It works fine with a wandboard QUAD, but it should work on the BBB too. You can connect it direct to BBB ethernet port and have all advantages of WLAN (no electrical influences from network). And you can put it far way from your DAC.

A search for that comes up with a 3G/4G mobile hotspot. That's not the same as a WiFi dongle. :confused:

It works in different modes and also in WIFI. The smaller one is the TP-Link TL-WR702N Wireless Router, recommendation from HiFiFUINO.
