@Raymond I'm an average user, and have done very little poweruser stuff. After reading through all the posts, I still don't know if any fix has been identified. I'm attaching my alsa-info.sh, and can make any changes and provide results as long as clear instructions are provided.
Please let me know what you see and if you'd like more information.
