# PulseAudio Configuration for seeed-voicecard # PulseAudio Configuration for seeed-voicecard
Following this guide if you want to use your seeed-voicecard as a default source/sink of pulseaudio. Follow this guide if you want to use your seeed-voicecard as a default source/sink of pulseaudio.
### Prerequisites
1. Download PulseAudio
```
sudo apt install -y pulseaudio
```
2. PulseAudio Profiles
```
cd seeed-voicecard/pulseaudio
sudo cp pulse_config_4mic/seeed-voicecard.conf /usr/share/pulseaudio/alsa-mixer/profile-sets/seeed-voicecard-4mic.conf
sudo cp pulse_config_6mic/seeed-voicecard.conf /usr/share/pulseaudio/alsa-mixer/profile-sets/seeed-voicecard-8mic.conf
```
3. Add `udev` Rules
During the system start, when the card "seeed4micvoicec" is detected, the PULSE_PROFILE_SET variable will be set in the udev database, and PulseAudio will be forced to use `seeed-voicecard-4mic.conf`. Similarly, if the card "seeed8micvoicec" is detected, PulseAudio will be forced to use `seeed-voicecard-8mic.conf`.
```
sudo cp 91-seeedvoicecard.rules /etc/udev/rules.d/91-seeedvoicecard.rules
```
