alsa-project/alsa-firmware issue #11 was opened 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.
