alsa-project/alsa-firmware issue #11 was edited from juanpc2018:  ``` $ pulseaudio W: [pulseaudio] module.c: module-combine is deprecated: Please use module-combine-sink instead of module-combine! W: [pulseaudio] module-combine.c: We will now load module-combine-sink. Please make sure to remove module-combine from your configuration. E: [alsa-sink-RME Hammerfall HDSP 9632] alsa-sink.c: ALSA woke us up to write new data to the device, but there was actually nothing to write. E: [alsa-sink-RME Hammerfall HDSP 9632] alsa-sink.c: Most likely this is a bug in the ALSA driver 'snd_hdsp'. Please report this issue to the ALSA developers. E: [alsa-sink-RME Hammerfall HDSP 9632] alsa-sink.c: We were woken up with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail. ``` when i play any video or sound file, most of the time PulseAudio takes between 7 to 15 seconds to fill the buffer in proper order, audio is played in wrong order, chopped, like stutter. i have tested /etc/pulse/deamon.conf s24le to s24be problem persists. forced sample rate to 48Khz, i remember hdsp9632 worked ok on U/Kubuntu 10.04 & 10.10 Now 20.04.4 LTS has problems. im using Liquorix 6.3 Kernel. ``` $ sudo apt show alsa-firmware* Package: alsa-firmware-loaders Version: 1.1.7-1ubuntu1 Priority: extra Section: multiverse/sound Source: alsa-tools Origin: Ubuntu Maintainer: Ubuntu Developers <ubuntu-devel-discuss@xxxxxxxxxxxxxxxx> Original-Maintainer: Debian ALSA Maintainers <pkg-alsa-devel@xxxxxxxxxxxxxxxxxxxxxxx> Bugs: https://bugs.launchpad.net/ubuntu/+filebug Installed-Size: 211 kB Depends: fxload, udev, libasound2 (>= 1.0.24.1), libc6 (>= 2.4) Homepage: https://www.alsa-project.org/ Download-Size: 25,0 kB APT-Manual-Installed: yes APT-Sources: http://archive.ubuntu.com/ubuntu focal/multiverse amd64 Packages Description: ALSA software loaders for specific hardware $ sudo apt show alsa-tools-gui Package: alsa-tools-gui Version: 1.1.7-1ubuntu1 Priority: extra Section: universe/sound Source: alsa-tools Origin: Ubuntu Maintainer: Ubuntu Developers <ubuntu-devel-discuss@xxxxxxxxxxxxxxxx> Original-Maintainer: Debian ALSA Maintainers <pkg-alsa-devel@xxxxxxxxxxxxxxxxxxxxxxx> Bugs: https://bugs.launchpad.net/ubuntu/+filebug Installed-Size: 1.002 kB Depends: libasound2 (>= 1.0.24.1), libc6 (>= 2.29), libfltk1.1 (>= 1.1.6), libglib2.0-0 (>= 2.35.9), libgtk-3-0 (>= 3.0.0), libgtk2.0-0 (>= 2.8.0), libstdc++6 (>= 5.2) Homepage: https://www.alsa-project.org/ Task: ubuntustudio-audio Download-Size: 220 kB APT-Manual-Installed: yes APT-Sources: http://archive.ubuntu.com/ubuntu focal/universe amd64 Packages Description: GUI based ALSA utilities for specific hardware ``` Issue URL : https://github.com/alsa-project/alsa-firmware/issues/11 Repository URL: https://github.com/alsa-project/alsa-firmware
