# 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"
|
||||
```
|
||||
|
||||
|
||||
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==""
|
||||
ATTR{id}=="seeed4micvoicec"
|
||||
ATTR{number}=="1"
|
||||
|
||||
looking at parent device '/devices/platform/soc/soc:sound':
|
||||
KERNELS=="soc:sound"
|
||||
SUBSYSTEMS=="platform"
|
||||
DRIVERS=="seeed-voicecard"
|
||||
ATTRS{driver_override}=="(null)"

SUBSYSTEMS==""
|

|
||||
```
|
||||
|
||||
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
|
||||
pulseaudio --start # start pulse at first
|
||||
pactl info # check the setting
|

### 6-Mics Circular Array Kit and 4-Mics Linear Array
|
||||
|
||||
|
||||
1. Download pulseaudio
|
||||
```
|

sudo apt install pulseaudio
|

pulseaudio --k

```
|

|

|

sudo cp seeed-voicecard.conf /usr/share/pulseaudio/alsa-mixer/profile-sets/
|

```
|
||||
|
||||
3. Edit `udev rules`
|
||||
|
||||
During the system start, when the card "seeed8micvoicec" 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
|

|
||||
# Seeed Voicecard
|
||||
ATTR{id}=="seeed8micvoicec",ATTR{number}=="1",ENV{PULSE_PROFILE_SET}="seeed-voicecard.conf"
|
||||
```
|
||||
|
||||
|
||||
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}=="seeed8micvoicec"` and `ATTR{number}=="1"` with command `udevadm info -a -p /sys/class/sound/card1/`:
|
||||
|

pulseaudio --start # start pulse at first
|

pactl info # check the setting
|
||||
|

# The output should be like this

### 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`

### Load audio drivers statically
|
||||
### (it's probably better to not load these drivers manually, but instead
|
||||
### use module-udev-detect -- see below -- for doing this automatically)
