For a fews weeks, i had asked why i haven't sound in Firefox and have sound in other applications (amarock, Kaffeine, ...).
I was advised to enable pulse audio in PCC and now i have sound in all applications and firefox.
However, I find that the sound quality is less.
I use the sound card XONAR D2 and his sound driver is SNDVIRTUOSO, but it's ALSA (not pulse).
On my KDE desktop, as user, in pulse control volume, it's written : "CMI8788 oxygen hd audio. No possibility to change to SNDVIRTUOSO where sound is in best quality and has more force.
So with pulse audio enabled, the trimming of the sound in the volume control is 100% and with the driver SNDVIRTUOSO (ALSA) at 50% for the same trimming.
And i haven't the same pleasure to use my sound card: more with SNDVIRTUOSO ans very less with Pulseaudio.
So, i have the choice to return to ALSA (no sound i Firefox, but best sound quality with music or movies) or not enjoy the sound quality of my card, but have sound in Firefox.
Moreover, KDE has removed all sound devices but kept only the pulseaudio server !
Has anyone the same problems ?
Thanks for your advice and assistance.
