Ubuntu Sound Card: Zero Output

Job ID: 38354961

Budget: $30 – $250 USD

I'm currently struggling with my Ubuntu sound card; there is no sound output whatsoever. To combat this, I've already checked all settings and rebooted the system numerous times, but it remains silent. I haven't added any new software or made changes to the system before this issue arose.

I'm in need of an expert who has:
- a deep understanding of Ubuntu and its sound card configuration.
- the ability to diagnose and resolve hardware issues.
- the expertise to know if the issue lies deeper than the software itself.
Prior experience in resolving similar issues would be an advantage.
