Hi all, Unfortunately I cannot get the sound to work on my BeagleBoard (rev C5) with Ubuntu 14.04.3. I try to use the internal stereo out jack.
Playing any file fails with the following error: abarth@arm:~$ aplay /usr/share/sounds/alsa/Front_Left.wav ALSA lib confmisc.c:768:(parse_card) cannot find card '0' ALSA lib conf.c:4248:(_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:4248:(_snd_config_evaluate) function snd_func_concat returned error: No such file or directory ALSA lib confmisc.c:1251:(snd_func_refer) error evaluating name ALSA lib conf.c:4248:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory ALSA lib conf.c:4727:(snd_config_expand) Evaluate error: No such file or directory ALSA lib pcm.c:2239:(snd_pcm_open_noupdate) Unknown PCM default aplay: main:722: audio open error: No such file or directory The sound card does not seem to be recognized: abarth@arm:~$ aplay -l aplay: device_list:268: no soundcards found...
