Audio: Fedora has never built CONFIG_SND_SOC_WSA881X, the speaker-amp
driver the in-tree DTS requires; with it built out of tree the card
registers and plays. The din-ports message is a harmless warning. Also
record the S24_LE format defect and the sink-stealing traps (AirPlay,
Bluetooth, phantom headphone jack) that masqueraded as broken audio.
WiFi: every published modem firmware build (five distinct across nine
WOA versions) and kernel 6.12 all fail identically at QLINK, the link to
the SDR845 RF transceiver. This unit is an LTE SKU with working modem
history under Windows, fsg/fsc are blank, and the modem asks rmtfs for
unknown fsg_oem partitions. Fedora's tqftpserv also serves different
paths than the old aarch64-laptops one — the earlier instructions here
were wrong for it.
