MPD dead for usb Xmos device - Bromf - 02-May-2017
No matter which MPD version I select the Hardware page shows the following....
card 2: x20 [xCORE USB Audio 2.0], device 0: USB Audio [USB Audio]
Params(2,0)
closed
If I choose LMS any version then the Hardware page shows....
card 2: x20 [xCORE USB Audio 2.0], device 0: USB Audio [USB Audio]
Params(2,0)
access: MMAP_INTERLEAVED
format: S32_LE
subformat: STD
channels: 2
rate: 44100 (44100/1)
period_size: 441
buffer_size: 1764
or better depending on file played.
So, MPD does not work with my xmos usb device....
Seems to be .....
Audio glitches with certain USB High Speed (UAC2) audio devices.
Cause: USB driver bugs in Linux kernel
Fix: Add dwc_otg.fiq_fsm_mask=0x3 to the beginning of line in /boot/cmdline.txt
Where would I make these changes...??
BTW...you really..really have to get decent mpd software player..... client 175 is the pits...

Even on mobile/handphone devices. There is always a problem here or there. If you have a good one to recommend, i'd add it in.
Eventually I'd be coding up a universal Snakeoil client that'd work with most of the players.. Right now just going to finish up a 1.0.0 Snakeoil beta, and once that is out, I'd start working on the universal client.

Upgrade to firmware 0.1.5c, MPD should work then.
I have and it doesn't..... I do try as many fixes as possible before posting so as to ease your workload....:-)

Other working MPD distro....(Moode ) The USB High Speed (UAC2) is a known bug and has an MPD fix...... but not implemented in Snakeoil...?
If you have a good one to recommend, i'd add it in
ncmpcpp for console
Cantata...... Originally started as a fork of QtMPC, can be compiled with KDE support, Qt5 or Qt4 (runs on Linux, Windows and Mac OS X)
Mupeace for Android

First of all, is MPD working? I assume it to be a No because you said MPD is dead.
Can your confirm:
- If MPD is running
- Can your client connect to MPD
- and can you play music?

ncmpcpp for console
The client175 is included because it is a web client, work well in general. Other clients will still work.

Originally started as a fork of QtMPC, can be compiled with KDE support, Qt5 or Qt4 (runs on Linux, Windows and Mac OS X)This isn't practical to be included in Snakeoil. If you installed Cantata on another PC, then naturally it will be able to connect to the SnakeoilOS.. Remember SnakeoilOS is designed to be headless (no monitor or keyboard attached). Running heavy apps over a virtual desktop defeats the purpose.
Having said that, Snakeoil is designed to suit your purpose, if you want to start X and install Cantata, it can be done as you have full control over the OS.

RE: MPD dead for usb Xmos device - Bromf - 02-May-2017
Can your client connect to MPD
ncmpc......"Couldn't connect to MPD (host = localhost, port = 6600): Connection refused"
and can you play music?...... nope... because the xmos device is not recognised....as there is no UAC2 fix for high-speed usb devices for MPD. ?

Can you generate a diagnostics file, and attach it to this thread.
RE: MPD dead for usb Xmos device - Bromf - 02-May-2017
Don't know what's happening here...tried to access snakeoil mpd via cantata from Ubuntu (works fine to Moode MPD) but couldn't.
Went back to snakeoil and tried Client 175 again. (had ncmpc running via ssh but connection refused) added more files in client 175 and hit play.
The file I tried 2 hours ago started playing !!?? Then Client 175 behaves and ncmpc behaves...... scratches head...???
Will send diagnostic when it happens (ie not happens :-) ) again.
Xmos now shows in hardware..... irrespective of music playing or not.

FWIW pretty sure this line you you mention
Code:
'dwc_otg.fiq_fsm_mask=0x3' is specific to Raspberry Pi and not applicable at all in Snakeoil. That is meant to fix buffer underruns on Pi. And likely isn't applicable now. I compiled a RT kernel for my Pi a while ago and don't need that and high res streams fine with no pops/clicks/etc.

.Not that easy to incorporate into the existing versions of Snakeoil because libcurl is not available by default.
