Hi Hui, Thank you for reviewing my bug report so quickly.
When I gathered the original information in my bug report, standard analog stereo speakers were connected to the host system's 3.5mm analog audio output jack. The first test tone played by the bug report generator was heard via these speakers, however the second test tone was not. The test tone was the first and only time I have had successful audio output while using Ubuntu on this system. I do not know if it helps, but prior to installing Ubuntu I had Windows 10 installed and the audio output worked properly with the same external speakers. This would appear to confirm that host system hardware and external speakers are working properly. The problem only occurs when trying to use any version of Ubuntu (18.04, 19.10 and 20.20) Please let me know if I can provide any additional information or logs to investigate the problem further, and thank you for your help! -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1875199 Title: [HDA-Intel - HDA Intel PCH, playback] No sound at all Status in linux package in Ubuntu: Incomplete Bug description: No sound output.
