[alsa-devel] HDMI v. ICH8 on Dell XPS M1330
I figured this was more appropriate for devel, and not user. Sorry, if that's wrong. First, I'm using the 1.0.16 release tarballs. They work better than the in-kernel drivers, as they survive both suspend and hibernate, whereas the kernel drivers do not. I'm eager to see audio over HDMI working on my Dell XPS M1330. I'm pretty sure that this is /not supported/ at the moment -- if this isn't the case, please stop reading, and let me know the particulars. HDMI seems to be supported noted, but mainly for the ATI chips. I'm pretty sure the m1330 has a STAC9228 setup. None of the suggested model= module parameters succeeded in getting audio over HDMI, beyond what is autodetected without any parameter specified. model=5stack seems to show a digital SPDIF device added. If there is anyway I can help the core developers get HDMI audio working, I would be glad to help. I will post all the relevant information I can think of following; please let me know if other information would be helpful. I will gladly turn on any excessive debugging options needed. I am an ALSA n00b, but I will happily do any required work that I can do from this end.

The HDMI on HD-audio is currently handled equivalently with SPDIF. So, this device is the HDMI. Try to output this? Don't forget to adjust 'IEC958'-related mixer controls.

Actually, I've seen this as well, haven't really started to debug it. We define in the verb table of that system this: ;#21# <STAC9228> (SPDIF Out:Pin48) Jack:Other Digital, Digital, Black, A:A, S:0, Loc:Internal, Sp.8 (Bay, HDMI), Det:No, Imp:No ;#21#Config=0x185610A0 Notice we use the "Other Digital" as the jack. Is that possibly causing a problem? IEC958 shows up, but doesn't provide output to HDMI devices (that I've tested).

I've finally had a chance to test tonight. Toggling the IEC958 mute/unmute doesn't seem to change things via a default aplay. Using aplay -D hw:0,1 Noise.wav doesn't work because of set_params errors. Using the plughw form doesn't output audio, but seems to last the correct duratioI can happily try any suggested cvs/subversion/mercurial version, if needed.n of time it should. If aplay -l looks like this: **** List of PLAYBACK Hardware Devices **** card 0: Intel [HDA Intel], device 0: STAC92xx Analog [STAC92xx Analog] Subdevices: 0/1 Subdevice #0: subdevice #0 card 0: Intel [HDA Intel], device 1: STAC92xx Digital [STAC92xx Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 ... then I'm under the impression that aplay -D plughw:0,1 Noise.wav should work over HDMI, if everything connected correctly, yes?

Here you go; please find attached, or here: http://pastebin.ca/922821 ; I really do hope this helps.

It's a bit hard to judge right now. So far, many HDMI devices seem not working even though it appears set up properly. I've heard that ATI HDMI devices are working, but others are not well, e.g. on some devices only left channel is output and on others silent. Moreover, I'm not pretty sure whether HDMI is connected from the digital out of STAC codec. On many devices (e.g. ASUS ones), there is a dedicated codec for the HDMI transmitter. So, right now, it's total lack of (hardware) information, unfortuantely. We may try some verbs for HDMI that are not used in the current ALSA code, at least. These verbs were extended later... Takashi
Takashi, On the XPS M1330 (and XPS M1530) the SPDIF pin of the 9228 is hooked to the HDMI as these laptops were made before the HDMI portion had their own audio codec portion of the transceiver. So technically, it should be pretty simple ;) IDT PC Audio Demo/Linux/Test -----Original Message----- From: Takashi Iwai [mailto:tiwai@suse.de] Sent: Friday, February 29, 2008 5:57 AM To: Armando Di Cianno Cc: Tellman, Steven; alsa-devel@alsa-project.org Subject: Re: [alsa-devel] HDMI v.

Thanks, that's good to know. Do you know any other issues that stop HDMI audio working? IIRC, ATI board has a h/w switch in the video side to enable/disable its graphic-board HDMI, for example... Also, does STAC9228 codec support verbs for controlling HDMI, e.g. converter channel count (F2Dh, 72Dh) ? Takashi

I remember there being some work that the graphics guys had to do on the Windows side to get HDMI audio working for us. We have no control over the HDMI, we just enable our SPDIF pin and pump the bits. I can see if I can get a contact over at NVidia/ATI to help us out a bit if you want.

According to a post from an nvidia employee on nvnews, HDMI is currently unsupported. Sorry I don't have the link but you should be able to search for "Linux HDMI" on the site. Lee
It is possible that HDMI audio is pulled from an unknown i2c bus on the video chip. 3dfx did that a long time ago with their 3500 card for their tv tuner portion. I think at this point, unless Steven knows more, this may be unsupported until nVidia adds support in their driver or opens up part of the spec.

The HDMI device on that boards seems not actually a Realtek but SiI1392 or Chrontel HDMI transmitter. The board has another SPDIF out, which is likely the ALC883 one. But, there might be some other cases. Takashi

It is possible that HDMI audio is pulled from an unknown i2c bus on the video chip. 3dfx did that a long time ago with their 3500 card for their tv tuner portion.
I think at this point, unless Steven knows more, this may be unsupported until nVidia adds support in their driver or opens up part of the spec.
I googled some info about the nvidia G84** or G86** graphics core. They got the audio signal from the external audio device through spdif. For Dell M1330, the spdif configuration for the stac92** codec looks well, maybe the graphic driver can control whether the audio signal is allowed to transfer through the HDMI port?

Notice we use the "Other Digital" as the jack. Is that possibly causing a problem? IEC958 shows up, but doesn't provide output to HDMI

(that I've tested).
At a user level, this is definitely what I've experienced.
Are there any suggestions for testing if my current ALSA install /should/ work, or how to find out if something is misconfigured, or will simply not work?
Do you have the binary ATI driver installed? Several users have reported that it's required for HDMI audio to work.

In addition to anecdotal evidence, I can confirm that on my work machine the ATI video driver does seem to touch the audio. Interestingly it's the userspace X driver, not the in-kernel FGLRX module. rlrevell@chronopolis:~$ strings /usr/lib/xorg/modules/drivers/fglrx_drv.so | grep -i hdmi | grep -i audio ex_aHDMIAudioParameters Isn't DRM fun? ;-) Lee

A similar test with nvidia-drivers 169.12 proved fruitless (as expected). -- Armando Di Cianno http://dicianno.org/blog armando@dicianno.org armando@goodship.net

If it's a matter of a driver twiddling a bit on and off, maybe if someone with an @intel.com email address -- *hint hint* -- emailed NVIDIA tech guys, we might be able to get an answer as to what bits can be addressed to turn HDMI on and off, w/o modifying the NVIDIA binary driver. Does alsa-devel have a good report with NVIDIA, or any at all? -- Armando Di Cianno http://dicianno.org/blog armando@dicianno.org armando@goodship.net
