Test application from userspace, to test playback on sgtl5000 instead of aplay

srinivasanshanm — Sun, 17 Nov 2013 03:15:12 GMT

Dear I.MX Community,

Could you please provide me the test application from userspace in order to directly play a .wav file through the /dev/snd/pcmC0D0p node on SGTL5000 in I.MX28 BSP, instead of using alsa utilities ie., aplay , Kindly do the needful as early as possible,

Many Many thanks in advance

aplay is a software to play the sound. sgtl5000 is an audio codec that like as a sound card in the system.

They are different things.

e.g. to list the playback device

~ # aplay -l

**** List of PLAYBACK Hardware Devices ****

card 0: mxssgtl5000 [mxs_sgtl5000], device 0: HiFi Playback sgtl5000-0 []

Subdevices: 1/1

Subdevice #0: subdevice #0

to play .wav sound file

~ # aplay -D plughw:0,0 sound.wav
