ALSA: oxygen: prevent muting of nonexistent AC97 controls

2008-09-08T11:44:18+00:00

commit 3d839e5b87a70effc629c1cdbf77d837ef141919 upstream

Subject: ALSA: oxygen: prevent muting of nonexistent AC97 controls

The Xonar DX does not have CD Capture controls, so we have to check that
a control actually exists before muting it.

ALSA: emu10k1 - Fix inverted Analog/Digital mixer switch on Audigy2

2008-08-06T16:03:23+00:00

commit d2cd74b158d7214a556226e3312f9fb1de64d7ae upstream

On Audigy2 Platinum, the Analog/Digital mixer switch is inverted.
	https://bugzilla.novell.com/show_bug.cgi?id=396204

The patch adds a simple workaround.

There might be another device requiring a similar fix, too (or fix for
audigy2 generically), but right now I fix only the known broken one.

ALSA: hda - Fix DMA position inaccuracy

2008-08-06T16:03:21+00:00

commit 9ad593f6d326e7a4664e3856520f6c042f82a37f upstream

Many HD-audio controllers seem inaccurate about the IRQ timing of
PCM period updates.  This has caused problems on audio quality; e.g.
JACK doesn't work with two periods.

This patch fixes the problem by checking the current DMA position
at IRQ handler and delays the period-update via a workq if it's
inaccurate.

ALSA: hda - Fix wrong volumes in AD1988 auto-probe mode

2008-08-06T16:03:21+00:00

commit 43785eaeb1cfb8aed3cf8027f298b242f88fdc45 upstream

Don't create mixer volume elements for Headphone and Speaker if they
use the same DAC as normal line-outs on AD1988.  Otherwise the amp
value gets screwed up, e.g.

ALSA: trident - pause s/pdif output

2008-08-01T19:43:07+00:00

Commit 981bcead3f2279a1ec6fb5f2c57aff79ed61a700 upstream.

Stop the S/PDIF DMA engine and output when the device is told to pause.
It will keep on looping the current buffer contents if this isn't done.

ALSA: aw2 - Fix Oops at initialization

2008-06-23T10:06:23+00:00

The irq handler may be called before the proper initialization of hardware.
Call snd_aw2_saa7146_setup() before the irq handler registration.

[ALSA] hda - Fix "alc262_sony_unsol[]" hda_verb array

2008-06-09T14:21:42+00:00

I think that hda_verb array must have "terminator (empty array)".
But alc262_sony_unsol[] does not have it.
And it causes gcc-4.3's buggy behavior
with snd_hda_sequence_write().

sound: emu10k1 - fix system hang with Audigy2 ZS Notebook PCMCIA card

2008-06-06T09:16:06+00:00

When the Linux kernel is compiled with CONFIG_DEBUG_SHIRQ=y,
the Soundblaster Audigy2 ZS Notebook PCMCIA card causes the
system hang during boot (udev stage) or when the card is hot-plug.
The CONFIG_DEBUG_SHIRQ flag is by default 'y' with all Fedora
kernels since 2.6.23. The problem was reported as
https://bugzilla.redhat.com/show_bug.cgi?id=326411

The issue was hunted down to the snd_emu10k1_create() routine:

/* pseudo-code */
snd_emu10k1_create(...) {
	...
	request_irq(... IRQF_SHARED ...) {
		register the irq handler
		#ifdef CONFIG_DEBUG_SHIRQ
		call the irq handler: snd_emu10k1_interrupt() {
			poll I/O port   // <---- !! system hangs
			...
		}
		#endif
	}
	...
	snd_emu10k1_cardbus_init(...) {
		initialize I/O ports
	}
	...
}

The early access to I/O port in the interrupt handler causes
the freeze. Obviously it is necessary to init the I/O ports
before accessing them. This patch moves the registration of
the irq handler after the initialization of the I/O ports.
