[pulseaudio-discuss] Unable to make pulseaudio work on a Slackware based distribution (Kongoni)

Thu Dec 9 04:13:15 PST 2010

PA version is 0.9.22, udev support is build, hal support not.
Also now Im not in front of the "test" system, so I can't know if it's
producing sound, but I get this:

[kongoni at kongoni ~]$ pasuspender bash
[kongoni at kongoni ~]$ speaker-test -D hw:0 -c 2

speaker-test 1.0.23

Playback device is hw:0
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 8 to 16384
Period size range from 8 to 16384
Using max buffer size 16384
Periods = 4
was set period_size = 4096
was set buffer_size = 16384
 0 - Front Left
 1 - Front Right
Time per period = 5.444608
 0 - Front Left
 1 - Front Right
Time per period = 6.004962
 0 - Front Left
 1 - Front Right

Can't paste everything... too big :)
