HDMI Audio in Linux is Now Working on Cherry Trail mini PCs, OpenELEC 7.0 Image Released

Since Intel has decided not to officially support Bay Trail and Cherry Trail processors in Linux, and focus on other priorities, people who have tried to use HDMI audio in Linux with mini PCs or TV sticks based on the processors have always had issues. There’s a workaround for Bay Trail mini PCs with Linux 3.16 kernel, but so far I’ve never seen a Cherry Trail system working with HDMI audio in Linux. Luckily, Pierre-Louis Bossart has been working on support, and Piotr kasprzak has tried HDMI audio support with OpenELEC 7.0 and a patched Linux Kernel 4.5.1, and confirmed it to be working on Tronsmart Ara X5 Plus and Wintel 10 Pro mini PC powered by Intel Atom x5-Z8300 processor. This can also be verified in the kernel log with dmesg:

Review of MINIX NEO U1 Media Hub

We’ve already seen that MINIX NEO U1 has some impressive hardware to offer with a good thermal solution, and high-end chips for storage and WiFi, as well as some neats additions like RTC support. But obviously the most important is to find out how the box performs, so I’ve put it through it spaces with video playback and features testing, as well as some benchmarks. First Boot, OTA Firmware, Settings and First Impressions The device has three full-sized USB 2.0 ports, which become four once we had the provided USB OTG adapter to the remaining micro USB port. So I’ve connected a USB 3.0 hard drive, the RF dongle for NEO A2 Lite air mouse, a USB hub with a USB webcam, a USB keyboard, and the RF dongle for Tronsmart Mars G01 gamepad, as well as USB powered speakers to the micro USB port. After inserting HDMI, optical audio […]

ChromeCast 2.0 and ChromeCast Audio Announced for $35

Google released the original ChromeCast in 2013. The $35 device allows users to stream online video from your smartphone to your big TV, and since then Google and the community has brought various improvement to make more with the device, and thousands of apps can be installed in the little device. Google has now released a new ChromeCast, as well as ChromeCast Audio to stream audio to speakers. The hardware has been upgraded but the complete specifications are not available, but we do know ChromeCast 2.0 support 802.11 b/g/n and 802.11ac for higher quality 1080p video streaming, and Marvell tweeted about the new ChromeCast devices, so it’s likely another Marvell SoC has been used, maybe Armada 1500 Plus (88DE3108) [Update: ChromeCast 2.0 is based on Armada 1500 Mini Plus (88DE3006) dual core Cortex A7 processor] The new ChromeCast still works with iPhones, iPads, Android phones and tablets, Mac and Windows […]

MINIX NEO Z64W (Intel Atom Z3735F) mini PC gets HDMI Audio in Ubuntu

We’ve been able to run Ubuntu on Intel Atom Z3735F mini PCs, as well as other Linux distributions, for a while, but with an important caveat: HDMI audio would not work, so instead you had to use an external USB sound card to get any audio. Luckily the problem seems solved, as Linuxium has now released a script (audio-wifi-minix-neo-z64-release.sh) and relevant files that will patch your system to enable HDMI audio, and WiFI on MINIX NEO Z64W running Ubuntu. Ian Morrison (Liuxium) compiled a Linux kernel and the Wi-Fi driver, together with a modified DSDT (Differentiated System Description Table) table to fix an ACPI bug. He used John Pemberton’s Bay Trail Audio HDMI patch, as well as help from Paul Kendall for identifying the ACPI DSDT table bug, Bastien Nocera (hadess) for the wifi source code and DroidMote Server / Client for the wifi pointer. A quick demo shows WiFi […]

Popcorn Hour VTEN Review

Popcorn Hour VTEN a Linux based media player powered by Sigma Designs SMP8757 ARM Cortex A9 processor. Contrary to the many Android TV boxes I tested in the last few years, the device is dedicated to media playback, even though it has an App Store with 59 apps including YouTube, Facebook, and Twitter. I’ve already taken a few pictures of the device and board, so today, I’ll go through the user interface, quickly test the app store, go through my library of video test files, and check if HDMI audio pass-through is indeed working. Popcorn Hour VTEN User Interface I’ve connected VTEN to an Ethernet Gigabit switch, the HDMI port to Onkyo TX-NR636 AV receiver which itself is connected to LG 42UB820T 4K UHD TV, and the 5V/3A power supply. Pressing the On/Off switch at the back of the player will start it, and the boot takes just under one […]
