[alsa-devel] usb-audio: capture/playback break (implicit feedback related?)
by Eldad Zack 24 Jul '13

24 Jul '13

Hi, I'm still trying to figure out the issue with the capture and playback breaking with implicit feedback. I've disabled setting the sync ep for my device and did the following: start capture start playback stop playback Now, after a while, capture stops. I sniffed the usb traffic, and saw this: When I stop the traffic, the driver sets the alternate setting to 0 on the playback interface (2 for my device). So far so good. The first iso inbound packet has data in it, but starting from the second packet, it's all zero (in length). After a while, the device stops sending packets completely. The driver still tries, and evetually sets the alternate setting to 0 on the capture interface (3 for my device). Again, there is no implicit feedback involved here. I also ruled out playback interface being put into altsetting 1 (without us knowing it) when the capture was put into altsetting 1 by doing a GET_INTERFACE in set_format(). I am not sure if this an M-Audio issue, just my specific device (Fast Track C400) or maybe it appears in other devices. Anyone has an idea why this happens? I'd appreciate if anyone can test this on other devices. Clemens, since you recently added support for Roland devices that use implicit feedback, would you please test it and see if you get the same results, if you have time? If it helps, I can send the capture. Cheers, Eldad P.S. GET_INTERFACE adapted from drivers/usb/misc/usbtest.c: static int snd_usb_get_interface(struct usb_device *dev, struct usb_interface *iface) { int ret; char buf; ret = usb_control_msg(dev, usb_rcvctrlpipe(dev, 0), USB_REQ_GET_INTERFACE, USB_DIR_IN|USB_RECIP_INTERFACE, 0, iface->altsetting[0].desc.bInterfaceNumber, &buf, sizeof(buf), USB_CTRL_GET_TIMEOUT); if (ret == sizeof(buf)) return buf; return -ERANGE; }

[alsa-devel] [PATCH 00/27] devm cleanup, part #1, take #3
by Wolfram Sang 24 Jul '13

24 Jul '13

Here is another bit of cleaning up the devm usage. It is again removing the resource check with devm_ioremap_resource, because a) new drivers came in and b) coccinelle had a bug and missed to find a couple of occasions. Unlike last time, I think it is better if these patches go in via the subsystem trees to reduce merge conflicts. And there is one driver which I fixed manually because the original code needed some bigger update. All is based on v3.11-rc2 and the branch can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git devm_no_resource_check Other things which happened: I wanted to get rid of devm_request_and_ioremap, luckily other people are already working on it. Hooray! I already sent a patch series picking another low hanging fruit, i.e. drivers can skip devm_pinctrl handling if they are using only the default pin setup. And not devm related, there is still my proposal to rename INIT_COMPLETION to reinit_completion, that probably needs some more persistence... Yay, so much to clean up \o/ Regards, Wolfram Wolfram Sang (27): arch/mips/lantiq/xway: don't check resource with devm_ioremap_resource drivers/amba: don't check resource with devm_ioremap_resource drivers/cpuidle: don't check resource with devm_ioremap_resource drivers/dma: don't check resource with devm_ioremap_resource drivers/gpu/host1x/drm: don't check resource with devm_ioremap_resource drivers/i2c/busses: don't check resource with devm_ioremap_resource drivers/input/serio: don't check resource with devm_ioremap_resource drivers/iommu: don't check resource with devm_ioremap_resource drivers/media/platform: don't check resource with devm_ioremap_resource drivers/memory: don't check resource with devm_ioremap_resource drivers/mtd/nand: don't check resource with devm_ioremap_resource drivers/net/ethernet/stmicro/stmmac: don't check resource with devm_ioremap_resource drivers/pci/host: don't check resource with devm_ioremap_resource drivers/pinctrl: don't check resource with devm_ioremap_resource drivers/pwm: don't check resource with devm_ioremap_resource drivers/scsi/ufs: don't check resource with devm_ioremap_resource drivers/spi: don't check resource with devm_ioremap_resource drivers/staging/imx-drm: don't check resource with devm_ioremap_resource drivers/usb/phy: don't check resource with devm_ioremap_resource drivers/watchdog: don't check resource with devm_ioremap_resource sound/soc/au1x: don't check resource with devm_ioremap_resource sound/soc/cirrus: don't check resource with devm_ioremap_resource sound/soc/nuc900: don't check resource with devm_ioremap_resource sound/soc/pxa: don't check resource with devm_ioremap_resource sound/soc/tegra: don't check resource with devm_ioremap_resource sound/soc/txx9: don't check resource with devm_ioremap_resource thermal: ti-bandgap: cleanup resource allocation arch/mips/lantiq/xway/dma.c | 4 ---- drivers/amba/tegra-ahb.c | 2 -- drivers/cpuidle/cpuidle-kirkwood.c | 3 --- drivers/dma/mmp_pdma.c | 3 --- drivers/dma/mmp_tdma.c | 3 --- drivers/gpu/host1x/drm/hdmi.c | 3 --- drivers/i2c/busses/i2c-stu300.c | 3 --- drivers/input/serio/olpc_apsp.c | 3 --- drivers/iommu/tegra-smmu.c | 2 -- drivers/media/platform/coda.c | 5 ----- drivers/memory/tegra20-mc.c | 2 -- drivers/memory/tegra30-mc.c | 2 -- drivers/mtd/nand/mxc_nand.c | 5 ----- .../net/ethernet/stmicro/stmmac/stmmac_platform.c | 3 --- drivers/pci/host/pcie-designware.c | 12 ------------ drivers/pinctrl/pinctrl-imx.c | 3 --- drivers/pinctrl/pinctrl-rockchip.c | 5 ----- drivers/pinctrl/pinctrl-u300.c | 3 --- drivers/pwm/pwm-lpc32xx.c | 3 --- drivers/pwm/pwm-renesas-tpu.c | 5 ----- drivers/scsi/ufs/ufshcd-pltfrm.c | 6 ------ drivers/spi/spi-bcm2835.c | 6 ------ drivers/staging/imx-drm/imx-tve.c | 5 ----- drivers/thermal/ti-soc-thermal/ti-bandgap.c | 20 ++++---------------- drivers/usb/phy/phy-rcar-usb.c | 5 ----- drivers/watchdog/nuc900_wdt.c | 5 ----- drivers/watchdog/ts72xx_wdt.c | 10 ---------- sound/soc/au1x/psc-ac97.c | 3 --- sound/soc/cirrus/ep93xx-ac97.c | 3 --- sound/soc/cirrus/ep93xx-i2s.c | 3 --- sound/soc/nuc900/nuc900-ac97.c | 3 --- sound/soc/pxa/mmp-sspa.c | 3 --- sound/soc/tegra/tegra20_ac97.c | 7 ------- sound/soc/txx9/txx9aclc-ac97.c | 3 --- 34 files changed, 4 insertions(+), 152 deletions(-) -- 1.7.10.4

[alsa-devel] [PATCH 1/5] ASoC: dapm: Fix return value of snd_soc_dapm_put_{volsw, enum_virt}()
by Lars-Peter Clausen 24 Jul '13

24 Jul '13

The ALSA core expect the put callback of a control to return 1 if the value of the control changed and 0 if it did not. Both snd_soc_dapm_put_volsw() and snd_soc_dapm_put_enum_virt() currently always returns 0. For both functions we already have a 'change' variable which either contains 1 or 0 depending on whether the value has changed or not, so just return that.

[alsa-devel] [PATCH 1/2] ALSA: hda - Fix EAPD GPIO control for Sigmatel codecs
by Takashi Iwai 24 Jul '13

24 Jul '13

The EAPD GPIO is dynamically turned on/off for some machines with Sigmatel codecs, but this didn't work as expected, and it resulted in spontaneous lost of speaker outputs per HP plugging or power-saving. This patch fixes the bug by simply including spec->eapd_mask into spec->gpio_mask and spec->gpio_data bits.

The whole point of having ALSA core infrastructure for jacks is to avoid having to go round doing make work stuff like this. The fact that the kcontrols were introduced as a HDA-specific feature at all is of course a problem here...
