"aplay --help" does tell that it can support many sound file formats... and namely in this huge list, MPEG. after this, however, it says that some of these formats may not be available for my hardware. imagine some SB cards have included support for mp3, then I guess aplay can play MP3 on these. only on these. I am relly not sure, but if the user I m trying to help can hear sound, I am sure it can hear sound and that the mp3 has been decoded with a correct algorithm. I will follow your advice with the noapci paramet for kernel. that's a possibility. however if the problem was IRQ related, how can I detect this with classical linux commands ? > > ----- Original Message ----- > From: "Rene Herman" <rene.herman@xxxxxxxxx> > To: "Blue I" <blueeyedmemory@xxxxxxxxxxxxxxxx> > Cc: <alsa-user@xxxxxxxxxxxxxxxxxxxxx> > Sent: Thursday, June 21, 2007 3:04 AM > Subject: Re: alsa diagnostic > > > > On 06/21/2007 01:35 AM, Blue I wrote: > > > > > The card in use is using snd_emu10k1, and I asked the user to perform > this > > > command: > > > #aplay -D hw:0,0 the_user_soundfile.mp3 > > > the user tells me that the sound is not playing well > > > > While that doesn't surprise me... > > > > > : the first two seconds of the file are looped with glitches... exactly > > > the way like the trouble trying to be resolved with the user's xmms and > > > rhtymbox. > > > > ... that does.
