How can I get pulseaudio to sound as good as ALSA?

 PulseAudio and ALSA (Advanced Linux Sound Architecture) serve different purposes and have different designs. PulseAudio is a sound server that provides advanced features like per-application volume control and network audio streaming, while ALSA is a low-level sound subsystem focused on interacting with audio hardware. ALSA tends to be more straightforward and can provide a simpler and sometimes more direct path for audio, which might lead to the perception of "better" audio quality. If you want to make PulseAudio sound as good as ALSA, you can take some steps to optimize audio quality and performance: 1. **Configure Sample Rates and Formats:**    Check the sample rate and audio format settings in PulseAudio's configuration. These settings can affect audio quality. Open the PulseAudio configuration file, usually located at `/etc/pulse/daemon.conf`, and adjust the `default-sample-format` and `default-sample-rate` to match your audio hardware capabilities. 2. **Avoid Resam

sample-rate on pulseaudio changing alone

Question about the sample rate on PulseAudio changing on its own. If you're encountering a similar issue where the sample rate in PulseAudio is automatically changing without your input, you can try the following steps to diagnose and potentially resolve the problem: 1. **Check PulseAudio Configuration**:    - Review your PulseAudio configuration files, especially the `/etc/pulse/daemon.conf` or `~/.config/pulse/daemon.conf` file. Ensure that the sample rate is correctly set. Look for the `default-sample-rate` option and make sure it is set to your desired sample rate (e.g., 44100 or 48000).    ```    default-sample-rate = 44100    ``` 2. **Disable Module Suspend**:    - Some PulseAudio modules may automatically change the sample rate to save power or improve compatibility with certain hardware. You can disable these modules by editing the PulseAudio configuration. For example, to disable the module-suspend-on-idle, add this line:    ```    load-module module-suspend-on-idle ignore
