2016-08-04ALSA: hda - Fix headset mic detection problem for two dell machinesHui Wang1-0/+6
One of the machines has ALC255 on it, another one has ALC298 on it. On the machine with the codec ALC298, it also has the speaker volume problem, so we add the fixup chained to ALC298_FIXUP_SPK_VOLUME rather than adding a group of pin definition in the pin quirk table, since the speak volume problem does not happen on other machines yet.

2016-08-01ALSA: arm: Fix empty menuconfig SND_ARMEugeniu Rosca1-8/+7
commit 3c8f7710c1c4 ("ASoC: fix broken pxa SoC support") has removed the SND_ARM dependency from SND_PXA2XX_LIB and SND_PXA2XX_LIB_AC97, by moving these config entries outside of the "if SND_ARM ... endif" construct. However, by placing these 2 symbols right between the SND_ARM menuconfig definition and the first SND_ARM menu entry, the side effect is that the SND_ARM menu becomes empty and all the config entries caught between "if SND_ARM ... endif" no more belong to menuconfig SND_ARM, but to its parent (menuconfig SND).

Hence, the original driver always get the good frequency for 48000/96000/44100/192000. But for 32000, the mclk is incorrect, it should be 32000*128, but get 48000*128.

total number of members Currently, sound device drivers for PCI cards produced by Echo Audio support dimension parameter of element information. But the information has contradictions to the number of members of each element. I guess that this comes from the assumption that these sound cards are used only by 'echomixer' in userspace. But ideally, they should be used with usual ALSA control applications. This commit removes the contradiction. As a result, 'Monitor Mixer Volume' and 'VMixer Volume' elements are shown in usual ALSA control applications such as 'amixer' and 'alsamixer' in series.
