Have you had a chance to look through the tests and find suitable candidates?

I'm focus on Aplay and Aplay.headphone test now. But there are still two problems we need to fix first.

1. For the boards without sound card, we need to skip it.
2. It fails sometimes. We are still trying to find the reason.

Aplay:

Aplay.headphone:
https://stainless.corp.google.com/search?view=matrix&row=model&col=build&test=audio_Aplay.headphone&exclude_cts=false&exclude_not_run=false&exclude_non_release=true&exclude_au=true&exclude_acts=true&exclude_retried=true&exclude_non_production=false&days=14

This issue has an owner, a component and a priority, but is still listed as untriaged or unconfirmed. By definition, this bug is triaged. Changing status to "assigned". Please reach out to me if you disagree with how I've done this.
