Problems with default device for audio recording

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Dear friends,

I have detected some problems when I try to record sound in my Kubuntu 10.04 system.

The problem is that the "default" device for audio recording does not work but I have to select another device to do so. I always selected the "default" device for audio recoding but currently I have to select hw:0,2 device.

Another odd thing is that different programs show me different device. For example, Audacity shows me that I have the following audio recording devices:

- HDA Intel: ALC888 Digital (hw:0,1)
- HDA Intel: ALC888 Analog (hw:0,2)
- spdif
- default

The only one that works is hw:0,2.

But arecord shows me (when I execute "arecord -L") the following:

null
    Discard all samples (playback) or generate zero samples (capture)
default:CARD=Intel
    HDA Intel, ALC888 Analog
    Default Audio Device
front:CARD=Intel,DEV=0
    HDA Intel, ALC888 Analog
    Front speakers
surround40:CARD=Intel,DEV=0
    HDA Intel, ALC888 Analog
    4.0 Surround output to Front and Rear speakers
surround41:CARD=Intel,DEV=0
    HDA Intel, ALC888 Analog
    4.1 Surround output to Front, Rear and Subwoofer speakers
surround50:CARD=Intel,DEV=0
    HDA Intel, ALC888 Analog
    5.0 Surround output to Front, Center and Rear speakers
surround51:CARD=Intel,DEV=0
    HDA Intel, ALC888 Analog
    5.1 Surround output to Front, Center, Rear and Subwoofer speakers
surround71:CARD=Intel,DEV=0
    HDA Intel, ALC888 Analog
    7.1 Surround output to Front, Center, Side, Rear and Woofer speakers
iec958:CARD=Intel,DEV=0
    HDA Intel, ALC888 Digital
    IEC958 (S/PDIF) Digital Audio Output

Finally, in KDE system preferences for audio I get that I have 2 different audio devices for audio recording:

- HDA Intel (ALC888 Analog): it is said that it will try first x-phonon (CARD=0, DEV=0) and, if the latter does not work, it will try plughw (CARD=0, DEV=0)
- HDA Intel (ALC888 Digital): it is said that it will try first x-phonon (CARD=0, DEV=1) and, if the latter does not work, it will try plughw (CARD=0, DEV=1)

Where is the hw:0,2?? and how can I set the alsa system to use hw:0,2 as the default device for audio recording??

All of that would not be a problem but I also have an ubuntu 9.04 installed on a virtual machine (by using virtualbox) and audio recording doesn't work there. I suppose that it is becase of the virtual sound card is using default devices for playing and recording audio.

I must say that audio playback works fine in both host and guest systems. It is just audio recording.

Thanks in advance.
