Well, yes and no. I think we've established that there's no hardware support for decoding anything except MPEG2, but also that the machine is capable of doing most decoding in software.

On my bookworm desktop, I get this: $ pactl info Server String: /run/user/1042/pulse/native Library Protocol Version: 35 Server Protocol Version: 35 Is Local: yes Client Index: 13692 Tile Size: 65472 User Name: dsr Host Name: spike Server Name: PulseAudio (on PipeWire 0.3.65) Server Version: 15.0.0 Default Sample Specification: float32le 2ch 48000Hz Default Channel Map: front-left,front-right Default Sink: PulseEffects_apps Default Source: alsa_input.usb-Blue_Microphones_Yeti_Stereo_Microphone_REV8-00.analog-stereo Which says the things I expect: pulseaudio's interface is being supplied by pipewire, it's configured for 2 channel stereo, there's a USB microphone available and the output is being filtered through PulseEffects (which is doing equalization for me.) -dsr-
