Distortion after speechd spawning when using HDMI output

[marcecj]

Hi,

I've been having this issue for a while now (at least a year) where, when using my HDMI sound output (and only then), sound would suddenly become distorted (hard to describe, it sounds glitchy and there's a noticeable left/right delay). Up to now I just restarted pulseaudio as a workaround, but recently noticed that it always happened when starting KMail. Following this lead I found out others were having this problem and that it was triggered by speechd auto-spawning (see, e.g., https://bugs.kde.org/show_bug.cgi?id=401493). Setting DisableAutoSpawn in ~.config/speech-dispatcher/speechd.conf finally caused the issue to go away.

I don't know what exactly is causing this, but speechd is as far as I got. This is with speech-dispatcher 0.9.1 and pulseaudio 13.0 (although I've gone through several different versions of the latter by now).

This is very probably what was worked around in #198 . This is an issue inside pulseaudio which was triggered by the low latency requested by speechd. Please upgrade speech-dispatcher to at least version 0.10.0 to get the work around. Alternatively, uncomment the

AudioPulseMinLength 1764

line in speechd.conf.

Ah, so this was already taken care of in a newer version, guess I need to file a bug with Gentoo to get a newer version in (otherwise I would have tested that first). Also glad to see there's also a PR for pulseaudio :-) . Anyway, thanks for the quick response!
