This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- hirsute' to 'verification-done-hirsute'. If the problem still exists, change the tag 'verification-needed-hirsute' to 'verification-failed- hirsute'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

[Fix] The hardware is not capable of generating smooth audio output at the maximum volume that codec chip can be configured. A fix proposed to lower the maximum output volume using CS8409 equalizer. [Test Case] Use GNOME Settings / Sound Settings, set volume to 100%, play test audio for both right and left channels; set volume back to 70%, and repeat the same to compare to differences. While we don't have acoustic lab to perform precise measurements, the result was confirmed by partner. [Where problems could occur] This is to add a preconfigured, equalizer driver default values. This will introduce non-uniformed frequency response in comparison to that in the hardware preset. The net effect observable to general users is a lower maximum output volume. For those Hi-Fi users, audio output always takes additional calibration via extra software like ALSAEqual and/or hardware. [Other Info] By SRU we skipped a couple of refactoring changes in asound upstream tree, so additional changes to the original patch are required to backport. ========== original bug description ========== A cracking noises is noticed when doing audio playback from the built- in speaker when the volume is set >80.
