I tend to stick with 44.1 so it's good to know 48k could be trouble.

Hmmm, disabling ethernet isn't an option for ssh communication.

Yes, it is a matter for me too

So I made a udev rules that disables ethernet when the sound card is connected and re-enables it when the sound card is removed

 

Perhaps the 'LEAVE_ME_ALONE' comment could be worth checking out?

yes, it could but I haven't the card under the hand anymore 

Also, what did you roll back to get audio working again?

if I remember correctly, 

with the firmware of middle september, i got cracke in audio with ethernet enabled, which is the same with firmware from late April

but when I disable ethernet, USB is not working well anymore, even if there is no audio card, e.g. my keyboard does something very strange

and the sound card doesn't work well

but this could be due to the function I use to disable ethernet which seems to a hack and may be no more usable with recent firmware without making USB inusable.

so I did :

sudo rpi-update 994e46341bd190ef4ce6ee011e3f9fb8173e2bbf

to get the firmware from april 26th

and disable ethernet with : 

dhclient -r #release DCHP

echo -n "1-1.1:1.0" | sudo tee /sys/bus/usb/drivers/smsc95xx/unbind #disable the cheap

sorry, I have several cards from ESI and messed them every times !

I was thinking about UGM96 which works great at 48kHz (btw I didn't try it at 96kHz because I have enough troubles and headache with 48k)

But note, that I need to disable the ethernet to get input without crackles.

Good to know, thanks Antoine.

What was it that you rolled back?

BTW - can't be the UDJ card as that has no input but I think you have a different ESI card too.

hi, 

I couldn't try this and I don't know anything about mmap_emul but

I recently updated a Pi (in the middle september) and got crakle with an ESI UDJ 6 (2in/2out) which was working great before

then I downgrade to the version of april 26 2013, and it works again

Hi all,

I'm building a fresh rpi image and after installing hexxah's rpi-update and running it to update the firmware I got this message (not seen before):

"mmap_emul is set in /etc/asound.conf, disabling it as it is no longer necessary
If you are (for instance) using an external USB soundcard that needs mmap_emul,add the string LEAVE_ME_ALONE to your /etc/asound.conf as a comment
If you don't know what an /etc/asound.conf is, don't worry about this message"

So I guess my question is:

How do you know if your usb soundcard requires mmap_emul?

Also a heads up as I know a couple of people mentioned having sound problems recently and perhaps this may help.

This is most recent raspbian image btw.

Regards,

Julian
