Hi Jack, |
| 27 |
|
| 28 |
I don't wanted to pollute my posting with non-Linux details...but here |
| 29 |
they are: |
| 30 |
|
| 31 |
I habe a Teensy 3.6 by PJRC (=>https://www.pjrc.com/), which has an |
| 32 |
USB-port. This port can be switched between a lot of USB-devices... |
| 33 |
...one of them is an USB-audio device (output). |
| 34 |
The MK66FX1M0VMD18 uC has beside an FPU a DSP block. |
| 35 |
With a certain (open source) firmware this chip can be used as an |
| 36 |
synthesizer. |
| 37 |
|
| 38 |
To cut costs I wanted no USB dongle to play the sound ... I wanted |
| 39 |
to use my Linux PC as "Mega DAC"...so to say. |
| 40 |
|
| 41 |
Question is: |
| 42 |
How can I create such an "receiver" for USB Audio signals to play |
| 43 |
them live with my PC? |
| 44 |
|
| 45 |
Cheers! |
