Portable Music

Tuesday, March 5th, 2019

For some time, my portable music needs had been satisfied with a Sansa Zip Clip player and Soundmagic E10 headphones, but the breaking of the Sansa meant I needed to revisit that.

My current phone is a Huawei P-Smart, the previous Motorola having broken, got fixed and then given to my better half, because there was a delay fixing the Motorola (in the end, easy and cheap) and I needed a phone: The Huawei, however is not ideal for a number of reasons:

1) It comes preloaded with too much tat. I’m quite zero-tolerance on un-neccesary apps and add-ons, something I’ve always done with PCs and continued with phones.

2) It can’t take a second SIM and a micro-SD, like the Swift 2 I dunked in the cut.

Still, it was cheap, and the battery lasts well, but:

3) The headphone output is just shockingly bad. Indescribeably bad, it sounds flat and lifeless unless you enable some Huawei proprietary shitty processing software, and when you do that, it seems to have a active dynamic range compression that actively compresses loud(er) sounds down in particularly clumsy way. It’s painful to listen to.

So the obvious choice of giving up on a seperate player and using the phone seemed to be out. I did fancy the award-winning Cowon Plenue D player, but £200 seemed a bit much given a few expenses of late.

The answer presented itself: Soundmagic’s new offering, the E11, comes in a Bluetooth version. That way, the crappy phone just presents a bitsream, someone that is competent can handle the D-A conversion, and I don’t risk tearing the headphone jack off the phone in my pocket, and if I end up with a phone with no 3.5mm jack (unlikely for a while, I’m too tight), no problem.

I’m a convert. I had my doubts, but the headpones are light and comfortable, the battery life seems OK, and the sound is as good as the wired E10s, all for considerably less than half the price of the Plenue D. Hell even the slight background hiss I’d noticed during my recent hospital stay turned out to be from the oxygen pipe I was wearing….

I’ve had a Volumio music player for a while: pretty good overall, but sometimes a bit prone to corrupt filesystems. Checking the website, there was a new version, so I thought I’d try it. It was….interesting. Cleverly done, with squashfs filesystem images and a data partition to save data, but using it gave me a few issues. First of all, the original Raspberry Pi model B I was using turned out to be too slow: the initial setup took 20 min to complete, and playing audio was glitchy as it couldn’t shift data down the USB fast enough. Changing to a Raspberry Pi2 fixed that, but then it dropped off the network. With no HDMI monitor nearby, this was impossible to troubleshoot, so I tried an alternative: I had a HP thin client lying about, and Volumio has a x86 experimental version, so with a CF-IDE converter and a CF card to replace the tiny flash disk in the HP, off I went. Working out a few bugs in the BIOS that make booting the CF and not trying to boot the external USB drives that just contain music took a while, but it worked, quite well, with 2 problems- firstly, the web interface and the view through Cantata didn’t agree, and secondly…
