Hi Ahn,

You should disable CONFIG_SND_SOC_HDMI_CODEC in the Linux kernel config.
The follow the AM335x Audio Driver's Guide about USB audio enable at:

Hi,
I want to hear audio through hdmi.
And I am also trying to listen to audio with a usb sound card.
If I disable CONFIG_SND_SOC_HDMI_CODEC, can I still listen to the audio with hdmi?

Ahn,

I'm sorry for misunderstanding. The CONFIG_SND_SOC_HDMI_CODEC should be enabled for HDMI audio output. The proper guide for HDMI audio is:
