The guest's audio stream ran about 3.5% short of realtime: 193 packets a
second where 200 were due, with no network loss at all. The client plays
at its own 48 kHz, so its buffer drained and underran every few seconds,
idle or loaded.
The graph was running 128-frame (2.67 ms) cycles. The 256 floor for VMs
matched on `cpu.vm.name`, which PipeWire reads from DMI and nesbox does
not provide, so it never applied, and neswire's 240-frame request was
rounded down to a power of two. A busy guest missed ~20 of those cycles a
second (pw-top ERR on neswire), and each missed cycle's audio never
reached neswire while the graph clock moved on.
- PipeWire is fixed at 240 frames, power-of-two rounding off: one cycle,
one 5 ms Opus packet, twice the headroom of before.
- neswire reads the graph position each cycle and fills exactly the
frames a missed cycle skipped, as silence, so the stream stays at
48 kHz whatever the scheduler does.

The seed was a release behind, so it now matches the tree it is migrated
onto. The scheduler, block-layer and TCP additions the tree ships are pinned
in the fragment, where the build checks them, rather than left to the seed's
defaults. Transparent huge pages move to always, since games map big heaps
without asking for them.
Clang builds the kernel now: whether thin-LTO is offered at all is decided
when Kconfig runs, so LLVM=1 applies to the config steps as well as the
compile, and missing tools fail before anything starts. Allocation and call
path hardening (init-on-alloc, freelist hardening, stack protector) and
debug info are pinned off alongside the speculation mitigations, and the
slab pin the minimal seed needs is restored.
