alsa: command not found on Debian Buster

Question

I am ingesting data into druid database event by event, but I want to delete all the events which are specific to a particular user.

For ex. while ingesting data I want to delete events for all the entries having name="Ram"

Solution 1

The person who says "alsa is deprecated" is incorrect. Pulseaudio is a sound daemon that runs on top of ALSA. ALSA is still there under the hood.

But it is true that your problem might be due to pulseaudio. Open pavucontrol and mess around with the options in there, that might help you.

Solution 2

Alsa is pretty deprecated. Now, most distro (including Debian) rely on pulseaudio to manage sound.

Do you have any pulseaudio running on your system ? If yes, it's probably the root cause of your problem. Anyway, i suggest forgetting about alsa and using a pulseaudio and of its mixer (pavucontrol is quite good). Inside this, you have a configuration tab where you can choose output.

On my laptop, by default, pulseaudio was sending sound to HDMI output ...

Can you please share more detailed information on how you are ingesting data into druid?

[Garvit Khamesra]

Through kafka indexing service

Can I do it someway dynamic? Because If my system removed 4 users how will I let druid know about this? Or can I update any record in druid?(Not lookup)

[Jainik]

If you can have any field in your CSV file like an active/inactive flag then it will be so easy to have a filter on that column and filter events while performing ingestion.

[Garvit Khamesra]

But if the user goes inactive after a month I injested the data. Then what would be the solution.

[Jainik]

Then why don’t you use filters at the time of querying data? If you do that then you do not need to update your data and you will have more control over the data filtering.

Please don't post an answer unless it actually gives a solution to the problem. You need to be more specific than "...mess around with...". It's best to only post a solution you have tried and tested yourself.

The site didn't give me any other option. I wasn't allowed to post a reply to the post that contained misinformation, otherwise I would have done that.
