Switch sound to HDMI in Lubuntu without installing additional packages

Question

I am trying to build a music player and while researching the behavior of other apps I have realized that some apps store the now playing list and the song id, so that same state is available when the app is started afresh.

1.) So how to implement this? Which technique will be faster?

Saving song id is simpler by using shared preferences but what about whole list of songs and other data associated with them ( like duration , title...). How to store them.

2.) Also some song that was stored gets deleted, so how to manager that?

I have already tried searching and came up with this but to no avail:

How to save "now playing" list of Music Player App in Android?

Solution

Try to put the following entry into /etc/asound.conf or your ~/.asoundrc:

pcm.!default = pcm.hdmi

This question is too broad. There could be a lot of possible ways to do this.

Can you list the possible ways? I have two qs. you can at least answer one of them if you know? Thanks. And I don't know why the -1 because as I have mentioned that I have searched for ways and also attached the link.

[Rahul Verma]

@JLT can you answer the qs please or atleast mention the links. I have been stuck on this qs for a while now.

Thanks, this worked, but I need to logout/login for the changes to take place, is there a command to reload the .asoundrc file? Preferably without requiring root.

The .asoundrc file is read by the ALSA library whenever a program opens some ALSA device the first time.

I have array list of song class objects which holds song's id, title and everything. How to integrate it with that?
