I'm trying to get pyAudio operational with a C-media mic/speaker card on a beaglebone black running ubuntu 13.04. After many permutations of attempts, I'm seeking help here - as I simply cannot get the combination of configuration and pyAudio to play nice here.
I've disabled the HDMI by modifying uEnv.txt: optargs=quiet capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN And I see my sound card listed: root@ubuntu-armhf:/home/ubuntu# cat /proc/asound/devices 2: [ 1- 0]: digital audio playback 3: [ 1- 0]: digital audio capture 4: [ 1] : control 33: : timer and: root@ubuntu-armhf:/home/ubuntu# aplay -l **** List of PLAYBACK Hardware Devices **** card 1: Set [C-Media USB Headphone Set], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0 Simple python code fails: import pyaudio p=pyaudio.PyAudio() s=p.open(format=pyaudio.paInt16,input_device_index=1,channels=1,rate=44100,input=True,frames_per_buffer=1024) with the following errors: root@ubuntu-armhf:/home/ubuntu# python audio_test.py ALSA lib confmisc.c:768:(parse_card) cannot find card '0' ALSA lib conf.c:4241:(_snd_config_evaluate) function snd_func_card_driver returned error: No such file or directory ALSA lib confmisc.c:392:(snd_func_concat) error evaluating strings ALSA lib conf.c:4241:(_snd_config_evaluate) function snd_func_concat returned error: No such file or directory Attempts to change the default card to '0' have failed as well. 2 Examples: 1. Per: http://ubuntuforums.org/showthread.php?t=1313071, adding root@ubuntu-armhf:/etc/modprobe.d# tail -1 alsa-base.conf options snd-card-usb-caiaq index=0 does not seem to set the default card to 0 (this is the setting used above) 2. Changing asound.conf per: http://feipengy.no-ip.biz/blog/2013/12/09/enable-audio-in-beaglebone-black/ Similar failure is observed from pyAudio. Any ideas? I suspect I'm missing something really obvious here. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
