The A20 driver for HDMI audio is almost done!

UPDATE 20-01-2020: Now the A20 HDMI Audio driver patches are submitted  and KODI images with working HDMI Audio are on our ftp

We blogged few weeks ago about the KODI image done for A20 and A64 by our friends Dimitar Gamishev and Stefan Saraev.

A64 had everything working fine, but the A20 image had no HDMI audio, as there is no such driver in the mainline kernel. This of course made A20 not useful for media center.

We decided to try to solve this problem by ourselves by writing this missing driver and today we have success!

The audio driver for HDMI is working, but is still far from complete as we have to add channel management etc, but with our driver we can hear audio via the HDMI with A20!

We will complete and send the patches to mainline after our Christmas-New Year vacation, so somewhere in January the KODI image (and of course all Olimex official images) for A20 will be updated and will have HDMI audio too!

Are you ready to play with Do-It-Yourself Alexa Speaker, WiFi SIP phone, WiFi walkie-talkie, Internet Radio player and broadcasting? Then the Open Source hardware ESP32-ADF is the right board to start with!

Today we made our first Alexa prototype:

and we spoke with ESP32-ADF running WiFi SIP phone, you do not need PC to make free calls all around the world to other people with VoIP phones!

Surprisingly there was no any lag caused by the WiFi and it works as good as the commercial wired SIP VoIP phones.

We add now MOD-LCD2.8RTP with touch screen on ESP32-ADF UEXT connector and write some nice graphical UI then will upload the VoIP phone demo code next week.

We do same for the Internet Radio player demo – nice graphical UI, so user can select which radio station to connect to.

 

It’s a pleasant surprise to see our AM3352-SOM in High-End Audio product at M.O.C. Messegelände München

It was noticed by our friend and Audiophile Boris Ribov from Technical University in Plovdiv, who went to visit M.O.C. Messegelände München.

Our guess is AM3352-SOM is used as communication board there handling USB, Ethernet etc communication.
