[alsa-devel] [PATCH] Enable loudspeakers in ALC889 for Acers and others
by ruben＠ugr.es 02 Jul '09

02 Jul '09

Hi all I managed to get sound working on my acer 6935, which has an ALC889 driven by the intel_hda driver The lack of sound seems to appear in other laptops as well. The bug report is at https://bugtrack.alsa-project.org/alsa-bug/view.php?id=4261 I know Takashi Iwai is familiar with the problems, since I used his workaround with hda-verb to get it working initially, so if he is free and wants to get this fixed, I'd be grateful (if anybody else can have a look, that'd be great as well). The patch is very easy (you can download it at the url above). I added snd_hda_codec_write(codec, 0x15, 0, AC_VERB_SET_EAPD_BTLENABLE, 2); at the end of patch_alc883 before the return. Please check whether there is a problem with other models; in that case a new patch_alc889 which calls patch_alc883 plus the line can be added, or more detailed checks on the pci ids can be done. Thanks for your time. Ruben

[alsa-devel] Problems with snd-hda-intel on hp 6930p (2.6.30)
by Rafael J. Wysocki 02 Jul '09

02 Jul '09

Hi Takashi, I have a problem with snd-hda-intel from 2.6.30 on an hp EliteBook 6930p, which is that the sound is not audible, although everything appears to work just fine. Except maybe that when the box is rebooted and KDE (3.5) is started, the master control is "muted" and the led indicator next to the keyboard shows "no sound". Then, changing the "muted" status of the master control doesn't change the state of the led indicator and vice versa (the two things appear to be totally independent of each other). Can you please tell me what I can do to debug this issue? Best, Rafael

[alsa-devel] laptop multichannel ethernet OR PCMCIA sound cards
by Matt Flax 02 Jul '09

02 Jul '09

We are after an ultra low latency connection to a multichannel in/out sound card for a laptop. We want a portable system and don't want to network to a different computer to achieve this goal. As we are after ultra low latency, we are interested in both PCMCIA and ethernet (gigabit) solutions. Is anyone aware of any such ultra low latency hardware ? Can anyone suggest any other solution for a laptop which is portable and not based on ethernet or PCMCIA ? I think that USB and firewire are good, but want even lower latency to the hardware if possible. thanks -- Matt Flax, BE, BSc, PhD Research Engineer National Acoustic Laboratories A Division of Australian Hearing 126 Greville Street Chatswood NSW 2067 Australia P +61 2 9412 6985 F +61 2 9411 8273 Please consider the environment before printing this email

[alsa-devel] [PATCH] Line In for Acer Inspire 6530G model
by Tony Vroon 01 Jul '09

01 Jul '09

The Line In connector is set up as PIN_IN by default, using VREF_HIZ. It is connected to both ADCs, so add it to both input selectors. Also add the ability to use the input mix (on a SoundBlaster one would call this "What You Hear").

Re: [alsa-devel] ALSA patch Nvidia 8 channel hdmi audio
by Pau Rodriguez-Estivill 01 Jul '09

01 Jul '09

I attach a patch to support 24bits and 32kHz, 44.1kHz, 48kHz, 96kHz, 192kHz, all rates that appears in the screenshot submitted by Alan Alan. I created also an asound.conf to correct the speakers positions. Since current driver only support 2, 4, 6 and 8 channels I specified it in the asound.conf but I'm not sure if this slave.channels should be fixed. The main problem is that by using asound.conf I didn't found any way to route to surround51 (or surround50 or surround40, ...) depending of the number of channels offered by the sink player. And when I play directly to hdmi, the AMP reports automatically the correct number of speakers involved. Of course it would be nice to have this routes hardcoded in the driver...

Re: [alsa-devel] PC speaker beeps in 2.6.30?

[Adding some more Cc's...] Am I the only concerned about this? My 2.6.30 is still silent w.r.t. old good PC speaker beeps, and I wasn't able to make it to produce any sound. Yes, as pointed out by others there is a control now, in alsa, and I can hear ugly and scary beeps from my stereo speakers (when they're turned on and when the control is un-muted). But that's.. not a solution/answer to the original question... ;) Thanks!

It's only the problem from speaker, not about the headphone, right? If so, the problem is likely the missing amplifier setup, which is usually powered up via COEF verbs or GPIO verbs (ALC888/1200 have no EAPD verbs). Try to install hda-verb program and check the command below. # hda-verb /dev/snd/hwC0D0 0x20 SET_COEF_INDEX 7 # hda-verb /dev/snd/hwC0D0 0x20 GET_PROC_COEF 0 Which value do you get?
