Cheap Savitech chip firmware stalls on rapid SET_INTERFACE / sample-rate renegotiation, eventually dropping off the USB bus and requiring a physical replug. Two fixes, both scoped to this exact device only: - snd_usb_audio quirk_flags (262a:10aa): fixed_rate + ctl_msg_delay + iface_delay, applied via /etc/modprobe.d during bootstrap. - WirePlumber: disable idle-suspend for the device's ALSA node so PipeWire doesn't repeatedly reopen the stream during normal use.
