Having read this I felt encouraged to buy an Aureon 5.1 USB MK.2.
I have been working at it for 4 days with very limited success.
After boot I can play a .wav file OK:-
]$ aplay -D plughw:1,0 bl_04.wav
Playing WAVE 'bl_04.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
When I try to record (with sound to the card input which gets through to the
PC speakers), however, I have no success
]$ arecord -f cd -t wav -D plughw:1,0 foobar.wav
Recording WAVE 'foobar.wav' : Signed 16 bit Little Endian, Rate 44100 Hz,
Stereo
sometimes I get just an empty file (44bits)
occasionally a longer file of silence
but most often:-
When I stop it with <cntrl> C but the console prompt does not return
and:-
]$ ps aux | grep arecord
user_id 2320 0.0 0.0 0 0 pts/6 D+ 15:47 0:00 [arecord]
(D = Uninterruptible sleep (usually IO))
After this happens aplay (in a different console) behaves similarly, no sound
and goes into a 'D' state.
I am using alsa-driver-1.0.14rc3
( configured --with-sequencer=yes --with-oss=yes
--with-cards=usb-audio,seq-dummy, dummy, virmidi)
alsa-lib-1.0.14rc3, alsa-utils-1.0.14rc2 on Fedora Core 4 with kernel
2.6.15.4. I also have a SiS sound card built into the MB but have not compiles
an asla driver for it.
I would be most grateful for any help or hints specially from anyone who has
an Aureon 5.1 USB MK.2 working successfully.
Here are various files which may be helpful:-
