Sluggish Audio Loading on AnkiMobile with Large Media Collection

AnkiMobile (iPhone/iPad) Help
3

I’m experiencing consistent playback delays regardless of whether Bluetooth earphones or the iPad’s built-in speaker.
I suspect that the following HTML code may be contributing to the issue.

<audio controls>
	<source src={{Sentence Audio}} type="audio/mpeg">
</audio>

I specify a filename (e.g., filename.mp3) in the Sentence Audio field.
When the field is formatted as [sound:filename.mp3], the audio loads significantly faster.

While the <audio> tag can offers standard playback controls, Anki’s native [sound:...] syntax appears to deliver better performance—especially when working with large media collections.

What are the best practices if I choose to continue using the <audio> tag?
