Bug 699978 – =www-client/chromium-79.0.3945.16 - ALSA lib /var/tmp/portage/media-libs/alsa-lib-1.1.9/work/alsa-lib-1.1.9/src/pcm/pcm_ladspa.c:1509:(snd_pcm_ladspa_add_plugin) Unable to find or load plugin '(null)' ID 1098, path '/usr/lib64/ladspa:/usr/lib32/ladspa'

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Techwolf 2019-11-13 07:10:34 UTC]

Running chromium as normal I get the following console feedback:

ALSA lib /var/tmp/portage/media-libs/alsa-lib-1.1.9/work/alsa-lib-1.1.9/src/pcm/pcm_ladspa.c:1509:(snd_pcm_ladspa_add_plugin) Unable to find or load plugin '(null)' ID 1098, path '/usr/lib64/ladspa:/usr/lib32/ladspa'
[28627:28627:1113/012931.364553:ERROR:alsa_util.cc(204)] PcmOpen: default,No such file or directory
ALSA lib /var/tmp/portage/media-libs/alsa-lib-1.1.9/work/alsa-lib-1.1.9/src/pcm/pcm_ladspa.c:1509:(snd_pcm_ladspa_add_plugin) Unable to find or load plugin '(null)' ID 1098, path '/usr/lib64/ladspa:/usr/lib32/ladspa'
[28627:28627:1113/012931.365508:ERROR:alsa_util.cc(204)] PcmOpen: plug:default,No such file or directory

The result is no audio on video playback/streaming.

Running "chromium --no-sandbox" resolves the problem, but is not ideal.

Reproducible: Always

Not a dupe. Pulseaudio not on system. This is a different error that has nothing to do with pulseaudio. That bug and patch only deals with pulseaudio.

It is a duplicate, only the summary in the other bug is a bit misleading.

Chromium-79 has an audio sandbox that allows only access to some files/pathes on the system (AFAICS hardcoded in chromium sources). By accident this sandbox is always enabled and there is no switch to disable it (except disabling sandboxing completely). Therefore Gentoo's PulseAudio (uses /var/run and not /run) and many other plugins are blocked.
