Hi,
I don't know if its best place to ask for a little help in what I think
are errors in linux audio driver, however I thought I ask for some
assistance.
I found a very old Creative Sound Blaster Extigy device and connected it
to my Acer Aspire e5-571g laptop. I was hopeful it would give me a 5.1
surround sound from an USB 1.1 (full speed) connection which: pacmd
list-cards command shows :
index: 2

<alsa_card.usb-Creative_Technology_Ltd._Sound_Blaster_Extigy-00>

What seems to work is output:iec958-stereo, a 2.0 digital stereo and
output:analog-stereo, 2.0 analog stereo.
When I switch to any multichannel output the sound that comes out of
most speakers seems to be delayed and is interrupted by "mettalic" noise.

It may be the case that USB 1.1 here is a limitation. Also maybe some
inkernel changes over the years made some impact on Extigy's driver. Can
any one help out what should I look for to get it to work?
Thanks,
