Enable PipeWire on Ubuntu 22.04

This guide is only for original Ubuntu out-of-the-box packages. If you have added a custom PPA like pipewire-debian, you might get into conflicts.

Ubuntu 22.04 has PipeWire partially installed and enabled as it's used by browsers (WebRTC) for recoding the screeen under Wayland. We can enable remaining parts and use PipeWire for audio and Bluetooth instead of PulseAudio.

Starting from WirePlumber version 0.4.8 automatic Bluetooth profile switching (e.g. switching from A2DP to HSP/HFP when an application needs microphone access) is supported. Jammy (22.04) repos provide exactly version 0.4.8. So, we're good.

Based on Debian Wiki, but simplified for Ubuntu 22.04.

Magento Scaling Hypotheses

Magento’s checkout throughput can increase to at least 8 times its current capacity and up to 26 times more in ideal conditions.

1. The current checkouts per hour limit for large, real-world Magento stores is 4,500
2. This limit cannot effectively be increased with more and/or better hardware
3. The improper type handling in Magento’s SQL code is the cause of the current limit
4. If one SQL query is fixed, large Magento stores can scale to a new, real-world limit of 120,000 checkouts per hour
5. For commodity hardware, this new limit might be 36,000 checkouts per hour

After having many deadlocks due to a high order volumne I've applied the these fixes to the core. Some can be found in a Magento forum. Before the fixes we could only process 1 order every 5-10 secs. Updating to Magento 1.8 is currently not an option but in 1-2 months.

1st Deadlock

Mage_Sales_Model_Abstract::_afterSave must be removed and replaced with afterCommitCallback. This is important to move the grid update (of sales_flat_order_grid) out of the transaction.

2nd Deadlock

Rewrite the method of the Mage_CatalogInventory_Model_Observer::reindexQuoteInventory() to remove the price reindexing from the transaction. That index process will also be fired in event sales_model_service_quote_submit_success.
