    DVD-ROM/RW issues on a laptop


    I am using a Winbook laptop with dvd-rom/dr-rw drive and dual boot XP/Ubuntu

    I use XP for digital music production
    Software: Cubase and Reason
    Hardware: Tascam US-122 USB audio/midi interface
    Maudio USB midi keyboard

    So, in XP, I use an external USB audio card for producing and recording sound, the resedent sound is unused.

    Recently I noticed that I was having sound issues in Linux. i could get system sounds and email sounds, but I no longer had access to my volume control icon and playing from audio CD's was not possible. When ad audio CD was put into the player and I ran a default CD Player program from the Applications menu I get a drive error.

    Tried playing a movie in xine (star wars IV) and I got video for the FBI warnings and then before the main menu crashed with this message:

    The source can't be read. Maybe you don't have enough rights for this, or source contains no data (ie: no disc in drive) (Error reading from DVD)

    More shows:
    audio_decode error: unknown buffer type: ??????? (repeates a large number of times with different decimal combinations each time.

    info from exiting xine:
    This is xine (X11 gui) - a free video player v0.99.3.
    (c) 2000-2004 The xine Team.
    libdvdread: Encrypted DVD support unavailable.

    Ok so when booting I get Buffer I/O error messages for hdc (my cd drive)

    output from dmesg(this was long, it pretty much repeats):
    error=0x54
    ide: failed opcode was 100
    end_request: I/O error, dev hdc, sector 7760
    Buffer I/O error on device hdc, logical block 1940
    hdc: command error: status=0x51 { DriveReady SeekComplete Error }
    hdc: command error: error=0x54
    ide: failed opcode was 100
    hdc: command error: status=0x51 { DriveReady SeekComplete Error }
    hdc: command error: error=0x54
    ide: failed opcode was 100
    end_request: I/O error, dev hdc, sector 7768
    Buffer I/O error on device hdc, logical block 1942
    hdc: command error: status=0x51 { DriveReady SeekComplete Error }
    hdc: command error: error=0x54
    ide: failed opcode was 100
    end_request: I/O error, dev hdc, sector 7776
    . . .
    Buffer I/O error on device hdc, logical block 1960
    hdc: command error: status=0x51 { DriveReady SeekComplete Error }
    hdc: command error: error=0x54
    ide: failed opcode was 100
    end_request: I/O error, dev hdc, sector 8884
    Buffer I/O error on device hdc, logical block 2221
    hdc: command error: status=0x51 { DriveReady SeekComplete Error }
    hdc: command error: error=0x54
    ide: failed opcode was 100
    end_request: I/O error, dev hdc, sector 8884
    Buffer I/O error on device hdc, logical block 2221

    OK, so I am fairly confused because I have had no problems until about a week ago. Now I am in a mad rush trying to figure what I have been doing that might have offset something that would cause such a sideeffect.

    Only thing I came up with is when rebooting from XP to enter Linux, I left the USB connections to the Audio/Midi interface in when Linux booted. Perhaps it attempted to recognize the hardware. however, linux has no idea of how to install this Tascam audio device so I couldn't imagine what could have been overridden.

    Other related issues:

    No sound from quicktime, flash . . . (however, can play streaming radio???)

    Is it a sound card issue or CD-ROM issue. By the way, not a problem with hardware, everything works A OK in XP.

    Thanks in advanced

    US-122

    I have a US-122 also, but sadly can offer no help on your problem, being a complete beginner to Linux (I abandonned Ubuntu and went and paid for Suse!)
    I am running vmware on linux and xp in that to use the us-122 but am still having problems as Linux keeps taking the soundcard before vmware allows windows to use it. My intention is to make recordings throught the sound card. Do you do this and if so how?
