I want to play any audio(.wav,mp3) file using a command like(aplay /path /to/audio/file.wav).
When I try to play using “aplay” coomad I got error.

The document about audio is Quectel_SC206E_Series_Linux_QAUDIO_API_Reference_Manual_V1.0.0_Preliminary_20240407.pdf
Please refer to this document and use the relevant API to play audio.
I have sent it to you by email.

Hi @keven.wu-Q

Thanks for your quick response.

I have gone through the document that you shared. and that use “qaudio-api-test” command but I wants to use “aplay”(using alsa) command. Please share way to play audio using aplay.

keven.wu-Q · January 23, 2025, 1:22am

During development, we used the tinyalsa tool, not the alsa tool.
So aplay cannot be used for the time being.
Unless you develop and port it separately.

Sachin_1296 · January 24, 2025, 5:09am

Hi @keven.wu-Q

Thanks for your quick response.

Is there any command in tinyalsa by which I can play audio file.

Apart from audio I want to interface AR0234CS camera with sc206e. Is there any way detailed document to interface other(non default) camera to SC206E.
