Meerkat Bluetooth Speaker Musings

I thought that I would list the results of using Bluetooth to connect to speakers.

I have 3 Bluetooth devices: and Insignia Stereo Speaker, Echo, and Trekz Titanium bone-conducting headphones.

After pairing the Insignia works, but the speakers are just fair. The Echo has much better sound and pairs well after giving Alexa instruction to pair. The Trekz is great with the day long live and clear sound. It’s like the sound from an old stereo.

Yesterday, I hooked up the Echo to the Mercat. After playing for about a half hour the sound became scratchy. This also happens with the Insignia, often it is scratchy from the start.  But it has never (fingers crossed) happened with the Trekz.

So I am wondering, do the processors get overworked? It never happens when the Echo plays my Amazon music. I would think that the audio signal is not being decoded when the distortion could occur.

So I am asking the group for explanations of this phenomena.

Example of “Rare” Customer Service for PC’s

Above is a “same day” response from Emma to an issue I reported on Cecilia’s System76 AIO (all in one) desktop PC.   The PC is out of it’s 1 year warranty but with System76, they continue to provide software support for the life of the PC (at no cost to the customer).

The issue was a Canonical update that issued a flawed kernel in response to the Meltdown/Spectre fiasco.

I’ll provide more detail at our club meeting for the 4 other Linux users in case this is or was an issue for them also.

How to Check if Your PC Is Protected Against Meltdown and Spectre (MS-Windows Only) . .

For all Windows users . . . in addition to the official MS patches, there are a second set of required actions to fix the Meltdown & Spectre security flaws.

Be careful as these updates are needed for the UEFI & BIOS firmware update & can brick your PC if done incorrectly!

Meltdown & Spectre Security Flaws . .

 

This is the most “widespread” security issue affecting virtually all PC’s for past 10-15 years.   To date, no known infections – – but the potential is there.

ALL#  cpu architectures have a degree of vulnerability (even phones).

# But it’s been reported that Raspberry Pi PC’s are immune from these flaws!

Initial patch  target date is:  Tuesday January 9, 2018 (for all major OS’s).

More detailed explanation about the issue – what it is and why Intel is most affected (different design, faster processing of page calls).
