+# PulseAudio Configuration for seeed-voicecard
+
+Following this guide if you want to use your seeed-voicecard as a default source/sink of pulseaudio.
+
+### ReSpeaker 4 Mic Array
+
+
+1. Download pulseaudio
+```
+sudo apt install pulseaudio
+pulseaudio --k
+```
+
+2. First, you need to write [a profile for pulse](https://www.freedesktop.org/wiki/Software/PulseAudio/Backends/ALSA/Profiles/)
+```
+cd seeed-voicecard
+cd pulseaudio
+cd pulse_config_4mic
+sudo cp seeed-voicecard.conf /usr/share/pulseaudio/alsa-mixer/profile-sets/
+```
+
+3. Edit `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.conf`. 
+
+    ```
+    # have a look at /lib/udev/rules.d/90-pulseaudio.rules
+    sudo vim /lib/udev/rules.d/90-pulseaudio.rules
+    # add the following lines at about line 87(behind the setting for some laptops and before the line GOTO="pulseaudio_end")
+    # Seeed Voicecard
+    ATTR{id}=="seeed4micvoicec",ATTR{number}=="1",ENV{PULSE_PROFILE_SET}="seeed-voicecard.conf"
+    ```
+    ![](./udev_rules_4mic.png)
+
+    The value of `ATTR{number}` can be found with:
+
+    ```
+    udevadm info -a -p /sys/class/sound/card0/
+    # or udevadm info -a -p /sys/class/sound/card1/
+    ```
+
+    For example, in Raspberry Pi, we can find `ATTR{id}=="seeed4micvoicec"` and `ATTR{number}=="1"` with command `udevadm info -a -p /sys/class/sound/card1/`:
+
+    ```
+    pi@raspberrypi:~ $ udevadm info -a -p  /sys/class/sound/card1/
+
+    Udevadm info starts with the device specified by the devpath and then
+    walks up the chain of parent devices. It prints for every device
+    found, all possible attributes in the udev rules key format.
+    A rule to match, can be composed by the attributes of the device
+    and the attributes from one single parent device.
+
+    looking at device '/devices/platform/soc/soc:sound/sound/card1':
+        KERNEL=="card1"
+        SUBSYSTEM=="sound"
+        DRIVER==""

+        KERNELS=="platform"
+        SUBSYSTEMS==""
+        DRIVERS==""
+    ```
+
+4. config `default.pa` and `daemon.conf`
+```
+sudo cp default.pa /etc/pulse/
+sudo cp daemon.conf /etc/pulse/
+```
+
+5. reboot raspberry pi and check 
+```
+sudo reboot

+pactl info  # check the setting

+
+### FAQ
+
+1. Default Sink/Source not right
+
+    Make sure there is no any other daemon or using the audio device. Then check profile and udev rules.
+
+    `pacmd list-sinks` and `pacmd list-sources` can be used to show the avaiable sinks/sources, after pulseaudio is started.
+
+2. Can't start PulseAudio
+
+    Check `default.pa` and `daemon.conf`
