X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=275353bb684ecfeb42f7a353fead81d43a01c519;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git ALSA: echoaudio: purge contradictions between dimension matrix members and 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.
