Bug#1058672: lsp-plugins: Bug in msmatrix code can cause speaker damage

Show all headers | View raw

Package: lsp-plugins-lv2
Version: 1.2.13-1
Severity: normal
File: lsp-plugins
Tags: upstream

Dear Maintainer,

according to upstream merge https://github.com/lsp-plugins/lsp-dsp-lib/pull/20
a bug in msmatrix code can cause

"really nasty full-scale buzzing/crackling of the speakers,
the kind of thing that could damage them (and since it is a periodic glitch and not
continuous, our power/thermal speaker monitoring [speakdersafetyd]
does not catch it as a problem)."

This mainly concerns aarch64 (Asahi) macs in general but may effect other
aarch64 systems too.

Because this will not be fixed soon (waiting for the next upstream
release) it may be useful to fix this bug by already backporting it.
