What Tsched 0?

If your hardware does not return accurate timing information (e.g. Creative sound cards) you can try to set tsched=0 to enable the interupt based timing which was used in 0.9.

How do I know if Pulseaudio is working?

Check the log output of PulseAudio, either in syslog, or following the instructions on https://wiki.ubuntu.com/PulseAudio/Log. Check the output of the command “pactl list” Open up the sound settings window from the sound indicator and check both the output and input pages.

How do I reset Pulseaudio config?

Here’s what I recommend, four steps:

  1. Check or add your settings at the bottom of /etc/pulse/default.pa for example, maybe you want to activate load-module module-echo-cancel.
  2. cd ~/. config.
  3. mv pulse pulse-old Hide the broken config, so pulseaudio can’t find it.
  4. pulseaudio -k Kills pulseaudio and it restarts automatically.

How do I restart Pulseaudio?

Here’s how to do it in Ubuntu 15.10:

  1. Launch Terminal.
  2. Run pulseaudio -k to kill the running daemon. You will get an error only if no daemon was running, otherwise no messages will appear.
  3. Ubuntu will attempt to restart the daemon automatically assuming there are no problems with the configuration.

What is config pulse?

DESCRIPTION. The PulseAudio sound server reads configuration directives from a configuration file on startup. If the per-user file ~/. config/pulse/daemon. conf exists, it is used, otherwise the system configuration file /etc/pulse/daemon.

What is Pactl in Linux?

Description. pactl can be used to issue control commands to the PulseAudio sound server. pactl only exposes a subset of the available operations. For the full set use the pacmd(1).

What is the difference between PulseAudio and ALSA?

As far as I know, ALSA is a package of many sound card drivers, and PulseAudio is a audio application that operate the sound data like mixing or equalizer.

What is module-udev-detect?

Automatically detect the available sound hardware and load modules for it. Supports OSS, ALSA, Solaris and Win32 output drivers, and the information is taken directy from them, not through udev. Do not use this together with module-udev-detect! If set to 1 the module will only try to load a single sink/source and than stop.

What are the device driver module parameters?

All device driver modules support the following parameters: Name for the sink (resp. source). Allowed characters in the name are a-z, A-Z, numbers, period (.) and underscore (_). The length must be 1-128 characters. The sample format, see supported audio formats for possible values (defaults to s16 )

How to use module-udev-detect with ALSA cards?

Let module-udev-detect look for the supported cards and then select the profile you want, that will make the right sinks show up. In addition to the general device driver options described above this module supports: The ALSA device to use. (defaults to “default”)

How to use module-udev-detect to find the right sinks?

Let module-udev-detect look for the supported cards and then select the profile you want, that will make the right sinks show up. In addition to the general device driver options described above this module supports: The ALSA device to use. (defaults to “default”) The desired fragments when opening the device. (defaults to 12)
