hi, i happened to have that ASUS mobo (P4R800-VM) which has an ATIIXP/AD1888 and both PCM and ac3 pass through works with SPDIF. but the board i am trying to get working has an ATIIXP/ALC655 and i had a look at the realtek site and they had some drivers (http://www.realtek.com.tw/downloads/dlac97-2.aspx?lineid=5&famid=12&series= 8&Software=True) which looks like they were based off alsa-1.0.4. just doing a quick diff i see that they added some SPDIF stuff amongst other things. after testing and some code diffing this is what i figured:
alsa-1.0.4 broken atiixp-spdif broken alc655-spdif realtek-alsa-1.0.4 broken atiixp-spdif working alc655-spdif alsa-cvs working atiixp-spdif broken alc655-spdif i am going to try and hack together some combination of realtek-alsa-1.0.4 and alsa-cvs and see if what i figured is right or not. it would be great if one of the alsa developers can look into realtek-alsa-1.0.4 and merge those changes into alsa. cheers, alex > -----Original Message----- > From: Takashi Iwai [mailto:[EMAIL PROTECTED] > Sent: Tuesday, May 25, 2004 2:45 AM > To: Alex Song > Cc: '[EMAIL PROTECTED]' > Subject: Re: [Alsa-devel] ATI IXP SPDIF > > > At Mon, 24 May 2004 16:16:42 -0700, > Alex Song wrote: > > > > hi, > > > > i am trying to get SPDIF output working on ATI IXP/Realtek > ALC655 and i am > > using atiixp.c from cvs (version 1.9) and linux kernel > 2.6.5. i tried > > playing back wav files through aplay and ac3 files with > ac3play and i > > couldn't get any output from either SPDIF over AC97 or > SPDIF Direct. analog > > output is fine. from the cvs logs i gather that SPDIF on > ATI IXP should work > > for some cases at least, has anyone got it to work? if so with what > > files/hardware/settings etc? > > it works fine on my test machine. it's an ASUS mobo (forgot the > model). > > % ac3dec -C some-48k.ac3 > > or > > % aplay -Dplug:spdif foo.wav > > but the direct SPDIF mode doesn't work... > > -- > Takashi Iwai <[EMAIL PROTECTED]> ALSA Developer - > www.alsa-project.org > ------------------------------------------------------- This SF.Net email is sponsored by: Oracle 10g Get certified on the hottest thing ever to hit the market...
