Pulse Audio 12

PressAudio, the multiplatform sound server designed to work with POSIX compliant systems, has received its new update with many improvements.

Among the improvements of Pulse Audio 12 We can mention better latency with the Bluetooth A2DP profile, which also improves A / V sync, more accurate latency with AirPlay devices, the ability to prioritize HDMI output over S / PDIF output, HSP support for more Bluetooth headsets and the ability to enable output and input in macOS.

PulseAudio 12 also adds support for stereo output from Steelseries Arctis 7 headphones and microphone input from Dell Thunderbolt TB16, a new reverb option that can be used for Speex echo cancellation, a new module. module-always-source, better detection of Traktor Audio 6 and a better support for digital input from various USB sound cards.

Intel HDMI LPE driver enhancements, default Bluetooth A2DP profile

Users upgrading their system to PulseAudio 12.0 will be able to choose the default Bluetooth A2DP profile instead of the HSP profile. The Intel HDMI LPE driver no longer causes CPU issues and it works great with sound systems.

The module-ladspa-sink module and the argument “sink_input_properties” have been added and the module-augment-properties module has been updated to use XDG_DATA_DIRS in .desktop files and the module-pipe-sink module, as well as the module-switch- on-connect which now ignores virtual devices.

Lastly, PulseAudio 12 makes status files unreadable by all users in system mode, la esdcompat tool no longer appears if esound support is disabled, changes the qpaeq component for Qt 5 and changes its license from AGPL to LGPL, in addition to bringing compatibility with the Vala language and the GNU C library in version 2.27. You can download PulseAudio 12 from its official website.

    This may be the reason why it has been going for a few days, I have the latest version of LXLE installed and suddenly without touching anything it stopped detecting the sound card, I have reinstalled the OS again and it has found it again , although at times it disappears because if the sound.

    Has anyone else had problems?

    You are right. Or I have had to give more weight to Alsa, trying to leave pulseaudio to the bare minimum probably thanks to this update. I've had to fiddle around starting with aplay -l to find the right profile and add it to ~ / .asoundrc
