Short version: your laptop speakers, headphone jack, and built-in mic show up as nothing in Linux, even though the drivers are already there. The BIOS quietly tells the audio chip to use an old, speaker-less mode. One tiny tweak flips it back. This gist wraps that tweak in DKMS so it keeps working after kernel updates and is easy to undo later.
Tested on a Zenbook S16 UM5606GA (AMD Ryzen AI, Strix Point) running Linux 7.0.9, June 2026.

| In Ethereum, a contract can be written so that it returns a value for eth_call. | |
| A Dapp can then check for success or error value of eth_call, before calling eth_sendTransaction, | |
| to take advantage of eth_call effectively being a "preview" of the code flow that the transaction | |
| will take. In traditional client-server, clients can't ask servers beforehand what's going to | |
| happen when the client makes a call; with Dapps contracts can be written so that clients can ask | |
| for a "preview" of what is going to happen, before any funds/ethers are actually utilized | |
| (eth_call does not cost any ethers). | |
| Note: it is possible that in between eth_call and when eth_sendTransaction is actually mined, |
| // -> Soldity | |
| // ********** | |
| // Your Soldity contract | |
| event Created(bytes32 indexed identifier); | |
| contract MyContract { | |
| function MyContract(bytes32 identifier) { | |
| Created(identifier); | |
