Preserve audio only quality with HLS

[mattiaz9]

I have this kind of playlist with a audio only quality along side multiple video resolutions:

#EXTM3U
#EXT-X-VERSION:4
#EXT-X-STREAM-INF:BANDWIDTH=3440800,RESOLUTION=1440x720,CODECS="avc1.640020,mp4a.40.2"
720p.m3u8

#EXT-X-STREAM-INF:BANDWIDTH=965800,RESOLUTION=960x480,CODECS="avc1.64001f,mp4a.40.2"
480p.m3u8

#EXT-X-STREAM-INF:BANDWIDTH=305800,RESOLUTION=720x360,CODECS="avc1.64001e,mp4a.40.2"
360p.m3u8

#EXT-X-STREAM-INF:BANDWIDTH=140800,CODECS="mp4a.40.2"
audio.m3u8

I see the player ignores the audio quality, but i would like to have an option to keep the audio quality in the qualities selector.

Is it possible to have something like this?
