Qualcomm Announces New Audio Platforms for Smart Speakers, Wireless Speakers, and Headphones

We've been witnessing the rise of virtual assistants for a few years now, and this has slowly transitioned into a new market trend. Amazon has been doing their thing with the Echo products for a bit, but lately we're seeing an increase in competition thanks to Google, Samsung and even Andy Rubin's Essential. These companies are seeing the smart home speaker system as a new, growing market and now Qualcomm hopes to help OEMs create even more of them.

With the first of their announcements, Qualcomm is really zeroing in on two different features with one of them being multi-room audio streaming. AllPlay compatible speakers make it easier for these products to play synchronized music across rooms, different music through different speaker zones, and also multi-channel wireless surround sound in the same room. The next area of focus for Qualcomm with the Smart Audio Platform is with virtual assistants.

They're able to provide advanced far-field voice technology to OEMs so their products can cut out background noise with special algorithms, cancel out echo and more. The company took things a bit further this week and announced additional audio platforms for what they're calling the next generation of wireless speakers, headphones and hearables. This comes in the form of new SoCs specifically for audio with each one being tailored to support the demands of different markets.

The CSRA68100 is designed for Bluetooth wireless speakers and it includes a next generation Audio Development Kit (ADK6.0) so developers have a suite of Bluetooth SIG qualified applications and profiles on hand. At the event, Qualcomm also announced the WHS9420 and WHS9410 single chip USB audio SoC platforms. These are specifically designed with USB-C connected audio devices in mind as the company sees USB Type-C becoming a standard in the next generation of products.

Qualcomm hopes the WHS9420 and WHS9410 chips are able to cover all three prices ranges (entry level and mid to high-end) with the WHS9420 being able to support with up to 192kHz/24-bit audio while the WHS9410 will be their entry level product.

How to Install Android 7.0 Nougat based LineageOS 14.1 ROM on Lenovo K4 Note

Lenovo launched the K4 Note last year and it is one of the most successful smartphones of all time. It has really good internals and also it is priced quite well at a very decent price. However, if you are one of the users of the smartphone, then you already know that the company is always lagging behind the software. Well, there is not a lot that you can do other than simply flashing a third party custom ROM. And if you are wondering how to do it, then you are in the right place since we will be showing you exactly how to do it.

Today in this tutorial, we will show you exactly how to install Android 7.0 Nougat based LineageOS 14.1 ROM on Lenovo K4 Note. But before we begin the installation, let's take a look at some of the features which it adds.

About the ROM

Wifi
Bluetooth
Audio
2G-3G Network Switch
Smooth
RIL
Camera
Sensors
Lineage Boosts
Hotspot
Fingerprint
All sensors

Now with that out of the way, let's take a look at some of the prerequisite that is required for this installation.

The first thing which you need to make sure is that you are creating a complete backup of your files. Since we will be completely wiping the internal memory of the phone, you will end up loosing all your files.
You also need to make sure that you are installing a custom recovery software. You can install any of your choices, however, we suggest you go for TWRP for this installation.
You also need to make sure that the battery in the smartphone as about 60-percent charge before you begin the installation. If your smartphone's battery dies during the installation, then you may end up with a completely bricked smartphone.
And lastly it is also necessary to make sure that you have downloaded the firmware file which is necessary for the installation. Without this file, you won't be able to proceed with the installation and hence we suggest you download the same from the link given below.

Installation

Assuming that you have downloaded the files given in the link above, it is now time to begin the instalaltion process.
The first thing which you need to make sure is that you copy the downloaded file to the smartphone.
Once done, simply turn off your phone and enter into the recovery mode. You can do this by pressing Volume Down + Power Key at the same time.
After this, once you are in the recovery menu, look for wipe and format option ⇒ wipe data, system, cache and Dalvik cache and initiate it.
Once done, now return back to the recovery menu and tap on Install.
Now it will ask you to browse for the firmware file which you had copied earlier. Simply navigate to the same and select it.
After that simply swipe to begin the installation.
Do make a note that the installation will take some time and hence we suggest you be patient with the same.
After it is done, before rebooting you can also choose to install the GApps.
Once this is done, your device will automatically reboot into the new ROM.

Do make a note that the first reboot may take a long time and hence we suggest you stay patient with the same. Having said, if you have any queries regarding the setup, then be sure to let us know by commenting down below and also stay tuned to Android Advices for more tutorials like this.
