SK-AM62B-P1: alsactl restore does not work

Part Number: SK-AM62B-P1

Tool/software:

Dear TI

I'm using ti-processor-sdk-linux-am62xx-evm-09.02.01.09.

When I execute "alsactl store -f config", it worked correctly.

But when I tried to restore it, it report below error.

root@am62xx-evm:~# sudo alsactl restore -f config
alsa-lib ../../../alsa-lib-1.2.6.1/src/ucm/main.c:1412:(snd_use_case_mgr_open) error: failed to import hw:0 use case configuration -2

If I did not use alsactl command to restore alsa config, could you let me know how to verify "alsactl restore" command with sample configuration file ?

    Hi Suren.

    Above link explains how to save / restore alsa config and my test command is exactly same how to save / restore via specific file.

    Is it possible to test it with SK-62B-P1 ?

    I think that it's your EVM issue.

    During boot-up, it reports same error message like below

    root@am62xx-evm:~# journalctl | grep hw
    Apr 28 17:42:26 am62xx-evm kernel: hw-breakpoint: found 6 breakpoint and 4 watchpoint registers.

    Hi,

    alsactl --no-ucm restore 

    should solve the problem.
