Dear Maintainer,

When using simplescreenrecorder with MP3 as audio codec, it fails with the
following messages:

[Muxer::AddStream] Using codec libmp3lame (libmp3lame MP3 (MPEG audio layer
3)).
[AudioEncoder::PrepareStream] Using sample format f32p.
[libmp3lame @ 0x55de0ebd90c0] Specified channel layout '2 channels' is not
supported by the libmp3lame encoder
[BaseEncoder::Init] Error: Can't open codec!
[libmp3lame @ 0x55de0ebd90c0] Supported channel layouts:
[libmp3lame @ 0x55de0ebd90c0]   mono
[libmp3lame @ 0x55de0ebd90c0]   stereo

Current versions:
- simplescreenrecorder 0.4.4-6
- libmp3lame0 3.100-6+b3

Note that simplescreenrecorder with MP3 was working fine a few months ago.
Unfortunately I cannot provide the respective versions of simplescreenrecorder
and libmp3lame0 at that time.
