У меня есть доска на базе IMX6Q и я хочу играть с PulseAudio. На моей плате три звуковых устройства:
# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: tlv320aic3xaudi [tlv320aic3x-audio], device 0: HiFi tlv320aic3x-hifi-0 []
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: tlv320aic32x4au [tlv320aic32x4-audio], device 0: HiFi tlv320aic32x4-hifi-0 []
Subdevices: 1/1
Subdevice #0: subdevice #0
card 2: imxhdmisoc [imx-hdmi-soc], device 0: i.MX HDMI Audio Tx hdmi-hifi-0 []
Subdevices: 1/1
Subdevice #0: subdevice #0
Устройство, которое я хотел бы использовать, это hw:1,0
:
aplay -D plughw:1,0 /usr/share/sounds/2.wav
Это работало нормально.
Но при запуске PulseAudio не обнаруживает устройства PCM. Когда я пытаюсь вручную настроить PulseAudio через
# pactl load-module module-alsa-sink device="hw:1,0"
Я получаю ответ:
Failure: Module initialization failed
и вручную, начиная с
# pulseaudio --system -vvvv --log-meta
возвращает:

Как я могу получить PulseAudio для загрузки устройства?
