我正在運行Raspberry Pi映像2012-07-15-wheezy-raspbian.zip並且我有一個安裝了RPi的CMedia 108 USB音頻適配器。JACK音頻連接套件jackd守護進程無法在RaspberryPi上啓動
嘗試啓動jackd使用內置的音頻
jackd -r -d alsa -d hw:0
無法啓動
JACK compiled with System V SHM support.

ALSA: Cannot open PCM device alsa_pcm for capture. Falling back to playback-only mode
configuring for 48000Hz, period = 1024 frames (21.3 ms), buffer = 2 periods
ALSA: mmap-based access is not possible for the playback stream of this audio interface
ALSA: cannot configure playback channel
cannot load driver module alsa
使用USB音頻
jackd -r -d alsa -d hw:1
立即退出,而不是在後臺運行。

任何想法?
是的,我理解了它....感謝反正。 – dudeking
