Re: USB DAC error (Chord 2Qute)

No matter what I set in the /etc/mpd.conf the message is always the same. I tried to comment out the full config file and I even tried to make syntax error in the config file but the response remains.
So I believe the speaker-test does not connected to the mpd.conf at all. I hope it helps to someone :-/

Re: USB DAC error (Chord 2Qute)

Can you try aplay instead? These error messages from speaker-test are useless.

aplay /dev/zero -D hw:D2Qute -f S32_LE -c 2 -r 48k

This should work and play silence until you stop it with CTRL+C.

Re: USB DAC error (Chord 2Qute)

Did not like the -r 48k (invalid argument) but I got this without it:

aplay /dev/zero -D hw:D2Qute -f S32_LE -c 2                                                                          ~

Re: USB DAC error (Chord 2Qute)

Hmm, maybe smaller period/buffer size? See if adding --period-size=256 --buffer-size=512 will change anything.

If this doesn't work, do this: disconnect the DAC, start dmesg -w in another window, connect it back, try aplay. Post everything printed by dmesg when the DAC is connected back and when aplay tries to play.

I get this (only the end of it, when I plugged the USB DAC back)

Re: USB DAC error (Chord 2Qute)

This doesn't look right. Do you have any USB 2.0 ports on this machine to try or only 3.0?

You said it worked on Ubuntu. Was it the same machine? Do you still have this Ubuntu installation? What kernel version does it have?

Re: USB DAC error (Chord 2Qute)

You are amazing!!! It works on the mobo's USB! But it's actually a halfway solution as I have to get it run on my custom made USB PCI Express card as this card has much better jitter.
Do you think that the USB PCI card does not installed properly?

Re: USB DAC error (Chord 2Qute)

It can be anything from hardware issue with the USB PCI card to a kernel bug. Did it work correctly with Ubuntu or did you use other USB port at the time?

ftom, it seems you hit report rather than reply:

I don't want to give it up as I believe I'm close to the finish line. What if I reinstall Ubuntu, can I find anything that I can copy to ARCH Linux?

Re: USB DAC error (Chord 2Qute)

Well, you could start with downgrading to some 4.8 or similar kernel from /var/cache/pacman/pkg. If you are lucky it's just a bug introduced in 4.10, if you are unlucky it may be a result of difference in kernel configs or patches between Arch and Ubuntu.

You probably don't need to install Ubuntu, but if you have the CD start it in "try ubuntu" mode, see if the DAC still works to make sure nothing bad happened to the PCI card in the mean time and (during playback) run

cat /proc/asound/card0/pcm0p/sub0/hw_params

to get a sample of some playback parameters which are guaranteed to be supported by hardware.

Re: USB DAC error (Chord 2Qute)

Hi Member.
