Hi,
Please can anyone let me know how to debug more or fix the following issue
I tried to play a wav file using aplay. Its giving the following error
root@host# strace aplay a2002011001-e02.wav execve("/usr/bin/aplay", ["aplay", "a2002011001-e02.wav"], [/* 15 vars */]) = 0 ... ... open("/dev/snd/pcmC0D0p", O_RDWR|O_NONBLOCK|O_CLOEXEC) = -1 EPERM (Operation not permitted) close(3) = 0 write(2, "aplay: main:722: ", 17aplay: main:722: ) = 17 write(2, "audio open error: Operation not "..., 41audio open error: Operation not permitted) = 41 write(2, "\n", 1 ) = 1
I tried to write a small program like the following
err = open("/dev/snd/pcmC0D0p", O_RDONLY); (I tried O_RDWR|O_NONBLOCK|O_CLOEXEC also) printf("err = %d, errno = %s.\n", err, strerror(errno));
Even the above failed saying "err = -1, errno = Operation not permitted."
I am running these as user "root".
The following are my snd devices
root@host:~# ls -l /dev/snd/ total 0 drwxr-xr-x 2 root root 60 Jan 1 1970 by-path crw-rw---- 1 root audio 116, 0 Jan 1 1970 controlC0 crw-rw---- 1 root audio 116, 24 Jan 1 1970 pcmC0D0c crw-rw---- 1 root audio 116, 16 Jan 1 1970 pcmC0D0p crw-rw---- 1 root audio 116, 33 Jan 1 1970 timer root@host:~#
There is nothing present in my /etc/asound.conf The following are few parameters in /usr/share/alsa/alsa.conf
defaults.ctl.card 0 defaults.pcm.card 0 defaults.pcm.device 0 defaults.pcm.subdevice -1 defaults.pcm.nonblock 1 defaults.pcm.compat 0 defaults.pcm.minperiodtime 5000 # in us defaults.pcm.ipc_key 5678293 defaults.pcm.ipc_gid audio defaults.pcm.ipc_perm 0660 ... ...
