    Smile poor sound & volume Ubuntu 9.04

    I have upgraded to ubuntu 9.04
    but have lost sound quality and have hardly any volume.
    and have tried most of the no sound threads but nothing has worked
    My sound chip is on the mobo using the SIS964 southbridge chipset which is compliant with the AC'97 v2.3 Codec
    I have run
    rod@rod-desktop:~$ lsmod | grep snd

    snd_intel8x0 37532 3
    snd_ac97_codec 112292 1 snd_intel8x0
    ac97_bus 9856 1 snd_ac97_codec
    snd_pcm_oss 46336 0
    snd_mixer_oss 22656 1 snd_pcm_oss
    snd_pcm 82948 3 snd_intel8x0,snd_ac97_codec,snd_pcm_oss
    snd_seq_dummy 10756 0
    snd_seq_oss 37760 0
    snd_seq_midi 14336 0
    snd_rawmidi 29696 1 snd_seq_midi
    snd_seq_midi_event 15104 2 snd_seq_oss,snd_seq_midi
    snd_seq 56880 6 snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_seq_mid i_event
    snd_timer 29704 2 snd_pcm,snd_seq
    snd_seq_device 14988 5 snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_rawmidi ,snd_seq
    snd 62628 16 snd_intel8x0,snd_ac97_codec,snd_pcm_oss,snd_mixer_ oss,snd_pcm,snd_seq_oss,snd_rawmidi,snd_seq,snd_ti mer,snd_seq_device
    soundcore 15200 1 snd
    snd_page_alloc 16904 2 snd_intel8x0,snd_pcm

    and a lot of the scripts in the no sound threads sadly no changes
    I have tried the diffrent sound drives in the sound volume preferances ie pulse , Alas, OSS, Realtek ALC655..... and no joy
    The sad part is the sound works perfectly in winXP partition using the lastest Realtek drivers and I don't want to return to using winXP
    So can anyone help

    I'm a newbie myself and maybe you already have done this, but I experienced some sound quality loss in Ubuntu, when I installed it first. My problem was that there was some noise disturbance/crackling when playing songs. What I found that I had to lower the PCM slider in the sound settings (Advanced option I think). After that it was a bit quieter, so I raised that master volume up and from then on it was fine. Maybe this helps!

    I face similar problem with my installation of 9.04. The sound works perfectly fine - nice and clear in the (dual boot) Vista installation on the same machine - yet in 9.04, it is barely audible. In my 9.04, from max setting, turning the volume 2 notches down is equivalent to shutting the sound off completely.

    I tried alsamixer as per the advice in this post

    Since I was using headphone, I turned the alsamixer headphone volume to max. What's more interesting was that somehow with alsamixer, I was able to turn the master volume to a much higher level than previously. The bottom line was this did seem to fix my problem.

    Hope this helps !
