Hello ALSA developers,
This problem with the USB sounds card has been reported a while ago,
and just been confirmed with latest kernel.
====================================================================
$ cat /proc/asound/cards
0 [I82801DBICH4 ]: ICH4 - Intel 82801DB-ICH4
Intel 82801DB-ICH4 with AD1981B at 0xc0000c00, irq 11
1 [U0x4fa0x4201 ]: USB-Audio - USB Device 0x4fa:0x4201
USB Device 0x4fa:0x4201 at usb-0000:00:1d.1-2, full speed
If I attempt to play a song using mpg123 or xmms, I get nothing, only maybe
click at beggining. I'm using in-kernel OSS emulation.
pavel@amd:/mnt/mp3.ptacek/Tanita_Tikaram$ cat /proc/asound/card1/pcm0p/info
card: 1
device: 0
subdevice: 0
stream: PLAYBACK
id: USB Audio
name: USB Audio
subname: subdevice #0
class: 0
subclass: 0
subdevices_count: 1
subdevices_avail: 1
pavel@amd:/mnt/mp3.ptacek/Tanita_Tikaram$
I tried unmuting everything using aumix.
cat /bin/bash > /dev/dsp1
fails to produce any sound, too.
===================================================================
Full bug report is here : http://bugzilla.kernel.org/show_bug.cgi?id=6576
It sure needs some helping hand, maybe someone can take a look into this.
Thanks,
--Natalie
