I don't have the device so I haven't done a full analysis, but it seems userspace (both udev and pulseaudio) got confused when a card was created, immediately destroyed, and then created again. However, at least one person in the bug report (martin djfun) reports that this patch resolves the issue for him. It also leaves a message in the log: "snd-usb-audio: probe of 1-1.1:1.1 failed with error -5" which is a bit misleading. It is better than non-working audio, but maybe there's a more elegant solution?

Right now, the clock source points to the internal clock (0x81), which is also valid. When the external clock source (0x82) is selected in the mixer, and the rates mismatch (if it's free-running it is fixed to 48KHz), xruns will occur. Set the clock ID to the clock selector unit (0x81), which then allows the validation code to function correctly.

But hdmi_chmap_ctl_put() returns -EBADFD when no PCM stream is assigned yet, and this results in an error message from alsactl. Although the error is harmless, it's certainly ugly and can be regarded as a regression. As a workaround, this patch changes the return code in such a case to be zero for making others happy. (A slight excuse is: when the chmap is changed through the proper alsa-lib API, the PCM status is checked there anyway, so we don't have to be too strict in the kernel side.)
