Original question:

AM625: AM625 arecord: main:831: audio open error: Invalid argument

AM625: aplay: main:831: audio open error: Invalid argument

Part Number: AM625

Command:  aplay jiewo.wav

Platform: AM625 SDK 9.0  SDK8.3

Issue:In SDK9.0,when TF card and U disk are plugged into the development board at the same time, audio playback will have a probability of failure.The probability of failure is about 50%.The errors are as follows:

root@OK62xx:/# aplay jiewo.wav
aplay: main:831: audio open error: Invalid argument

On the same embedded card, SDK8.3 does not have this problem.Therefore, hardware problems can be ruled out.

Please help me to complete the task.

Thanks,

Xiong wei

    Hi Xiongwei,

    Can you elaborate more on your setup? I assume you are booting the AM62x board with SD card. Along with the SD card, are you also having a TF card/U Disk connected on the board and seeing the issue. Can you share the logs and steps to reproduce.

    Best Regards,

    Hi, Suren

    Thanks for your reply.I am booting the AM62x board with emmc.The problem that the TF card and the U disk must on the board at the same time to produce the probability failure of audio playback. When I have a TF card and one U disk on the board the probability is going to be lower.When I haeve a TF card and three U disks on the board the probability is going to be higher.

    Can you give me some advice.

    Hi Xiongwei,

    Can you attach the entire boot log in both working and non-working scenarios?

    Also, can you reproduce the issue on our EVM with 9.1 SDK software? Or you are seeing this issue only your custom board?

    Best Regards,

    Suren
