I have a raspberry pi 3 model B+ with raspbian jessy lite from July.

**cat /proc/asound/version**

```
Advanced Linux Sound Architecture Driver Version k4.4.50-v7+.

```

I have a USB soundcard that has two 3.5 jack audio ports (one for mic and one for headphones) and I also have a bluetooth speaker.

What I want to do is to configure alsa to use the USB Soundcard(Set [C-Media USB Headphone Set]) only for microphone input and use my bluetooth speaker(bcm2358) as audio output. How can I do that ? I looked through similar questions and the answers I found didn't worked for me.

This question is related to this:

[Setup output and input audio on different cards](https://raspberrypi.stackexchange.com/questions/63072/setup-output-and-input-audio-on-different-cards)

He made it to get it work - but for me, it isn't working.

My configuration:
**aplay -l**

```
