to play the file on a different audio device to see if the issue is specific to hw:3,0.</P> <P>Then check and update the ALSA configuration to ensure it is correctly set up for the device, editing the /etc/asound.conf or ~/.asoundrc files.</P> <P>You can use dmesg to view the logs:</P> <LI-CODE lang="markup">dmesg | grep -i snd </LI-CODE> <P><BR />Best Regards<BR />Zhiming</P> Mon, 22 Jul 2024
