Hi Luca .
Sorry to bother you again.
My sound still not work.
I has used alsa_aplay command to play a mp3 file or wav file but it
doesn't work.
# alas_aplay -f cd /data/123.mp3
# Playing raw data '/data/123.mp3': signed 16 bit Little Endian, Rate
44100 Hz, Stereo.
And launching alsa_amixer -c 0, it still has show Segmentation fault.
Simple mixer control 'Master' ,0
Capabilities: pvolume pvolume-joined pswitch pswitch-joined
Playback channels: Mono
Limits: Playback 0 - 13
[1] Segmentation fault alsa_mixer -c 0
Could you give me a hint for that?
Thank in advance.
Best regards,
ehung
