Guys,
I have TDE building on fully updated Arch, but I'm trying to track down a 1-2
second delay I'm getting with sound events. This doesn't just affect the latest
TDE, but also began to effect older installs a few months back. I have the
default sound config presently. I have the following packages installed:
alsa-lib 1.0.25-1
alsa-plugins 1.0.25-2
alsa-tools 1.0.25-1
alsa-utils 1.0.25-3
alsaplayer 0.99.81-4
libpulse 2.0-2
pulseaudio 2.0-2
pulseaudio-alsa 2-1
The mixer in TDE uses pulse with only a single record and playback volume
adjustment. I have experimented with different /etc/asound.conf settings and
differing settings in ~/.pulse (via the alsa, pulse & sound wiki pages), but
have always found that the defaults work just about as good as anything.
For some unknown reason, I get a slight delay between the triggering of a
sound event and the actual sound. I understand this is due to different software
wanting to control the hardware at the same time from the thread about skype
audio from last week. What I need to know is whether anyone on the list has
experienced this scenario before and has perhaps found a solution. I have the
system hardware listed below. Let me know if you have any pointers or solutions.
Thanks.
