Linux sound subsystem maintainer Takashi Iwai of SUSE began the Linux 7.4 sound pull request by noting that "the AI flood continues" with there continuing to be a lot of new patches coming as a result of AI/LLM agents devising patches as well as uncovering new kernel bugs.

Takashi went on to explain that it was another busy cycle with changes in the sound subsystem from lots of core code hardening to new platforms and codecs as well. The core ALSA code has been hardened against some race conditions, there's a buffer leak fix in the compression offload code, race fixes in the JACK code, and other race conditions and more typical C bug fixes. The OSS sequencer emulation code has also been marked as deprecated for Linux 7.4.

On the hardware side, the Linux 7.4 sound updates include support for compressed audio playback on SOF IPC4 with Intel Tigerlake and newer. There is also AMD ACP 7.0/7.F sound IP support with SoundWire and the PDM controller. The new AMD ACP 7.0/7.F IP appears for upcoming Ryzen Zen 6 platforms.

There are also quirks for many different Intel/AMD laptops from the likes of Lenovo, ASUS, HP, AAcer, HONOR, MSI, and others.

New codec drivers are for the ESS ES9039Q2M, Nuvoton NAU83G60 amplifier, Senary SN624x SoundWire SDCA codec.

Also new is the Qualcomm QAIF driver for their Shikra platform.

If a company is worth $100B and drops to $50B in the course of a week, no one else became $50B richer from that stock, not even collectively.

That's based on the delusion that the company stock is "worth" anything in the first place. You sell, I buy, money changes hands, commissions are skimmed, taxes are paid, but no money is "destroyed" in the exchange. I sell, you buy, we lose money to the skim, but those skimming have and use that money for their own purposes, the money never goes away.

The delusion that TSLA is "worth" $400 per share, a delusion shared by banks which allow people to borrow against stocks, doesn't create or destroy money, it just means that people who bought at $40 per share get more money back than they paid, and that people who buy at $400 and sell at $40 get less back than they paid. In theory, shareholders own part of the company, but in practice almost all of that value is market perception, not based on actual assets that can be liquidated and distributed. At least not since retail investors got in the game 25+ years ago.

Bitcoin is the ultimate expression of this: there's literally nothing backing it up but perception, except in the case of BTC it's a negative sum game with all the energy and capital investment expended in processing the trades.

Oh, I agree, but you were the one talking about people losing their volatile investments and how you felt sad that your company’s stock had gone down. You weren’t talking about the act of exchanging shares, so I feel you’re moving the goalposts here…
