sonos cask stuck on 90.0-77070 despite newer 90.0-79210 being available (autobump/livecheck not triggering)

Verification

• I understand that if I ignore these instructions, my issue may be closed without review.
• I have retried my command with --force. (n/a — brew bump-cask-pr has no --force option and refuses outright for autobumped casks)
• I ran brew update-reset && brew update and retried my command.
• I ran brew doctor, fixed as many issues as possible and retried my command.
• I have checked the instructions for reporting bugs.
• I made doubly sure this is not a checksum does not match / SHA256 mismatch error (do not open an issue before trying to open a PR to fix first).
• I did not use AI/LLM to create this issue, or I disclosed the tool and model used; I will answer maintainer questions myself without AI/LLM.

Description of issue

The sonos cask hasn't received an autobump PR since #266514 (merged 2026-05-27), which bumped it to 90.0-77070. A livecheck-fix PR, #271413, was merged 2026-06-24, but no version-bump PR has followed since — despite a newer version being available:

• Currently packaged: 90.0-77070
• Latest available: 90.0-79210 — https://update-software.sonos.com/software/HBVQeC4A1l/Sonos_90.0-79210.dmg (HTTP 200, verified working)

I couldn't open a version-bump PR manually because Homebrew's own tooling refuses for autobumped casks (see command output below), and brew livecheck sonos is skipped for the same reason.

Testing the livecheck URL (https://www.sonos.com/redir/controller_software_mac2, used by the cask's livecheck block) manually returns 403 Access Denied from Akamai (errors.edgesuite.net), regardless of user-agent (tested default curl UA, curl/8.0, and a full Chrome UA string — all 403). Notably, even the plain https://www.sonos.com/ homepage returns 403 from this network, while the actual download CDN (update-software.sonos.com) returns 200 without any issue. This points to www.sonos.com blocking requests from certain (likely datacenter) IP ranges at the Akamai Bot Manager level.

I can't confirm this is actually happening on BrewTestBot's own CI infrastructure (I only tested from my own network), but the timing lines up: no successful autobump since the livecheck fix in #271413, despite a newer version having been live for a while. Since GitHub Actions runners are well-known datacenter IP ranges, it seems plausible they're hitting the same block, which would explain why the redirect-based livecheck strategy never succeeds anymore. Flagging this in case a maintainer can confirm from BrewTestBot's side, and/or consider pointing the livecheck strategy at update-software.sonos.com directly (or another endpoint that isn't behind this bot protection) instead of the www.sonos.com redirect.

We'd still love your contributions, though, so try another one
that is excluded from autobump list (i.e. it has 'no_autobump!'
method or 'livecheck' block with 'skip'.)
