I understand Firefox wants to have 48000Hz or it won't play. So, even if your DAC can do 96000Hz, you may need to specify a lower bit rate in the above config. The mic may also need specifying a particular endianess format and this may need to be different if you are using some websocket in FF, Vs the discord app directly. You could try S32_LE or S16_LE and various bit rates. The idea being to force alsa to use whatever format and rates the application may need/want, rather than passing through whatever the hardware is capable of.
