I have no display related issues, but I have a strange issue with audio.</div><div><br></div><div>I have an AMD Radeon RX560 connected to a Dell P4317Q display. When playing audio with a rate of 44.1kHz through DisplayPort while using AMDGPU drivers, no audio is produced. It works fine with audio of rate 48kHz. I do not have this problem in Microsoft Windows so it is unlikely to be a hardware problem.</div><div><br></div><div>It also doesn't appear to be isolated to a particular piece of software, as I get the same issue in VLC, Totem, Rhythmbox, or Firefox.</div><div><br></div><div>I've tried resampling the audio in ffmpeg and every common multiple of 12000 Hz works, whereas every common multiple of 11025 Hz fails to produce audio.</div><div><br></div><div>There are no logs in VLC or journalctl which seem to indicate a problem is happening. VLC appears to play happily, but no audio is produced.</div><div><br></div><div>I filed a bug report with the Fedora kernel maintainers in May, but have yet to receive any response.</div><div><br></div><div><a href="https://bugzilla.redhat.com/show_bug.cgi?id=1707035">https://bugzilla.redhat.com/show_bug.cgi?id=1707035</a></div><div><br></div><div>Please note that I'm presenting this to be a bug with audio of 44.1kHz rate, it is possible that something else is the cause.</div><div><br></div><div>I've tested this with a fair number of different variables and it seems very consistent, but I don't have enough kernel debugging knowledge to establish a firm causation.</div><div><br></div><div>If needed, I can help troubleshoot with some experienced guidance.</div><div><br></div><div>Thanks for your time and attention, please let me know what other data I can provide to help troubleshoot this issue.</div><div><br></div><div>-Ben Herrick</div><div>email: intrep@tauran.net</div></body></html>
